Among the different species of birds, blackbirds are one of the most interesting. They are small birds from the order Passeriformes, a genus of short-billed birds, which are characterized by their amazing appearance, hardy character and excellent singing abilities. The presence of a bird in a city park, forest or garden is necessarily accompanied by unsurpassed musical works, capable of surprising every passerby.

When the choir of blackbirds begins to sing, everything around seems to come to life and is filled with a fabulous atmosphere. Ornithologists treat the thrush with special attention, considering it a very valuable representative of the forest fauna of different regions.

Which bird has blue eggs?

Birds can have noble brown or light olive plumage with characteristic dark brown speckles. In addition, in nature there are individuals with a completely black body and small spots in the tail area. You can meet the blackbird in different countries and climate zones, which is due to the lack of particular whimsicality in terms of choosing a habitat. Many species are not considered rare and are very common. Among them:

• Nightingale;
• Robin;
• Bluethroat;
• Meadow mint;
• Black;
• Singer;

And many others.

The bird uses insects and earthworms that live in the natural litter as food. With the arrival of autumn cold weather, berries appear in the diet.

Description of the bird. Area

A significant part of the song thrushes, fieldfares and poultry birds live in the forests of the European continent, Asia and North Africa. Less common in this area you can find:

• the little blackbird, which prefers cold Siberia and the forest-tundra of North America;
• blue rock thrush that needs in dry mountain gorges and steep ocean shores. And although this bird can be found in Asia, Europe and Africa, the number of individuals is very small;

If we consider the example of a blackbird, then this forest dweller is capable of reproducing the most complex musical compositions, including a set of sad flute whistles, similar to the sounds of a deryaby singing. But in the latter they are very melancholic. The blackbird sings very loudly and cheerfully, filling the surrounding area with an atmosphere of fun and joy.

It is important to pay attention to the white-browed thrush. Representatives of this species are capable of singing local melodies, which are a vivid combination of falling and rising whistles. Depending on the region, the duration of the whistle may vary. For example: residents of city parks sing much differently than individuals living in the wild. For many years, scientists believed that the basis groups of white-browed birds consisted of birds who have family ties. But later it became known that young chicks are able to repeat the local melodies of adults, so the characteristic singing is passed on from generation to generation through diligent training.

Benefits for the ecosystem

Not everyone knows that the thrush performs a lot of useful tasks for the forest ecosystem. In spring and summer, birds destroy entire colonies of dangerous pests that disrupt the growth of trees, shrubs and other plants. Scientists have proven that in two weeks the blackbird flies to the nest about two hundred times, each time bringing a fresh portion of insects in its beak. Newborn, blind cubs remain in the care of adults for another fourteen days. At this time, they work hard and look for food. But even if the chicks grow up, their parents will not stop bringing great benefits to the ecosystem by spreading plant seeds in the process of eating plant food.

Blackbirds are one of the most important orderlies of forests, parks and gardens. Their role for the life of wildlife is very important.

A unique feature of all thrushes are their small eggs with amazing colors and shades. They are presented in blue or light green shades, which makes them stand out from the eggs of other birds. In rare cases, bird eggs are monochromatic. If specks appear on the shell, this indicates a certain type of pigmentation. During the development of the egg, a substance such as protoporphin is concentrated - a powerful photosensitizer that can absorb light from the sun's rays and convert it into oxygen, which is very important for the full growth of chick embryos.

Currently, more than 46 species of thrushes can be distinguished. Each of them lays unique eggs with a unique color. It is quite easy to distinguish one species from another. And although the differences in shades, shape and pattern are insignificant, if you look closely at them, you can understand how they differ. The most common are blue eggs, but other shades are also found in nature.

What kind of eggs do different types of thrush have?

The eggs of the American Swanson's Thrush, with their unique tail and wing tips, have a very beautiful, distinct blue color. The shell is covered with small specks brown color. The bird creates large nests based on dry grass, which it diligently collects throughout its life. Due to the unique feature of blue eggs, interest from ornithologists in the American blackbird continues to grow. In addition, the background blue color has many shades, including:

• greenish;
• grayish;
• bright turquoise;

At the same time, the specks are painted in a brownish-rusty color and have different sizes.

A modest representative of the family blackbirds called "hermit thrush" leads an overly shy and secretive lifestyle. The bird rarely shows itself and always hides in the thicket of branches from the surrounding danger. The plumage is colored brown, with some part of the chest distinguished by a blurry spot. The hermit thrush lays plain eggs with a delicate greenish-blue color. Their shells lack the speckles characteristic of eggs of other types. When creating a nest, the bird chooses tall trees that are difficult to reach for predators and are an excellent place where sunlight penetrates well;

In turn, song thrushes are represented quite extensive population in different regions peace. The color of the plumage is distinguished by faint olive and gray shades, while the color of the specks retains the tones of dark chocolate. The eggs are bright turquoise and have unique dark speckles of tiny size. In many cases, the speckles are also dark chocolate in color.

Features of the life cycle of a blackbird

The blackbird lays greenish eggs with a darkened olive tint. The shell is strewn with characteristic light brown spots. In addition, egg laying some individuals are represented by eggs with a greyish-green tint and large chocolate flecks. The lower part of the egg has a brown pigment.

Externally, representatives of the species look very solid and graceful. The plumage is completely black, and the beak is yellow. The rims around the eyes are orange or red (depending on the physiological characteristics of the individual). Compared to other blackbirds, this species stands out large size and characteristic way of life.

By studying the behavior of the thrush bird, you can notice a lot of unique features and secrets. For this reason, many ornithologists and true fans of birds are increasingly interested in the life cycle of such a common forest inhabitant.

The Araucana chicken breed is distinguished not only by its unusualness, but also by its antiquity. The homeland of these birds is South America. Araucana chickens appeared in one of the Chilean Indian tribes about 500 years ago. The first mention of this breed appeared in 1526, but it began to spread throughout the world much later. Pioneer chickens arrived in Europe at the end of the 19th century. Then some time was spent on development, and in 1965 the birds were finally accepted officially, receiving German standards for the Araucana chicken breed.

Description of the breed

When breeding poultry The Indians were guided by two principles: enhancing the fighting qualities of roosters and obtaining beautiful colored eggs from hens. According to one theory, it was possible to obtain an unusual multi-colored product from laying hens by crossing chickens with wild pheasants or similar birds. But this is just an assumption without solid evidence. One way or another, Araucana chickens are famous for two unusual distinctive features.

The Araucana is not a meat breed. Function of these birds consists of decoration and obtaining eggs. Araucana chickens have proven themselves very well as laying hens. And the blue color of the eggs makes this product especially popular. However, the appearance of the birds themselves is also very interesting and attractive. There are several breed standards that it must strictly comply with:

There are several non-compliances with standards that serve as a reason for culling birds from breeding:

• egg color that differs from that stated in the standards - blue or greenish-blue;
• narrow pointed body;
• the bird's angular figure or general awkwardness;
• presence of a very noticeable beard;
• fallen comb of roosters;
• lack of sideburns on the head on one or both sides;
• presence of a tail.

Possible color options quite a few: black-red, hawk, wheat-blue, white, golden-maned, silver-maned, wild, black, blue, wild blue and edged blue. All 12 varieties are officially included in the description of breed standards.

Advantages and disadvantages of the breed

Chickens that lay blue eggs have a stable psyche and a calm character. But, like any other breed, this one has its pros and cons. Among the advantages of the Araucanians, the following are noted:

• low demands on living conditions;
• ability to quickly adapt to new conditions;
• calm attitude to changes in ambient temperature;
• high survival rate in young birds, good health;
• early sexual development and the beginning of the egg-bearing period;
• beautiful and unusual appearance of both the birds themselves and their blue eggs.

Compared to the advantages, the breed has very few disadvantages:

• conflict of roosters, due to which they have to be kept separately from each other in order to avoid fights;
• hens lay eggs well, but do not hatch their future offspring at all;
• The Araucana breed is not very common, they are quite rare birds, so the price for purchasing them is quite high.

Productivity

Araucana gained popularity primarily due to the blue color of its eggs. Added to their beauty is the high productivity of laying hens. During the year, one chicken can lay from 160 to 180 eggs. Moreover, the period of oviposition begins quite early, at about six months.

It happens that the beginning of this process is delayed until ten months of age, but this is rather an exception to the rule. Such a delay is usually influenced by external factors. For example, poultry obesity, which a diet will help combat. It is also worth considering the time at which the hen herself was born. If she belongs to an autumn or winter brood, this may also cause a delayed start to the laying period.

In general, Araucana chickens lay eggs very well. Moreover, they do not reduce their performance either during molting or during various stressful external factors. Only moving can interrupt the egg-laying process for a short time.

Weight of laid eggs varies between 56-72 grams. In the first oviposition, the eggs are quite small, and in subsequent oviposition their size increases. There are dwarf Araucana hens, which also lay blue eggs, but are smaller in size - from 45 to 50 grams.

This breed is also not bad as a meat product; the carcasses look good and taste good. But, given the price and difficulties in breeding, Araucana is still most often used as a supplier of beautiful eggs.

Since representatives of the Araucana breed are unpretentious, their maintenance is no problem for either professionals or amateurs. It is enough to comply with the basic conditions to keep birds healthy and production levels high.

Chicken coop

The place of residence for pets should be prepared in advance. It is necessary to have perches and nests that need to be located at a sufficient height. Each hen should have 30 cm of perch. One nest is enough for 5-6 laying hens.

The coop should also have provisions for feeding and water. During use, it will be necessary to regularly and thoroughly wash and disinfect them. You also need a separate container for mineral feed, into which sources of calcium are poured: coarse sand, chalk, gravel, crushed shells.

When using a chicken coop, it is important to equip an area for the birds to walk. Araucana chickens do not fly well, but you still need to fence the area from above using a chain-link mesh or canopies. This is to protect the birds from possible attacks by predators. In addition, awnings will provide shade, which is very useful on hot sunny days.

If the region has cold winters, then you should think about heating in advance. Birds tolerate cold temperatures down to -8°C well, but lower air temperatures can already be dangerous. Therefore, at such times, the chicken coop needs additional heating.

As mentioned above, Araucana cockerels are very conflicting creatures. They cannot stand other males around them. Therefore, you should not keep two or more individuals together. male. The best option would be separate enclosures for a family of 8-9 birds: 7-8 hens and one rooster. Also, you should not keep the Araucana in the same area as other breeds, regardless of gender. This is fraught with both conflicts and breeding problems.

Feeding

Feeding birds of this breed does not present any difficulties. Food is selected taking into account the opportunities provided by the habitat. The diet is generally the same as that of other birds: grain, garden plants, food waste, root vegetables. In summer you need to give more grass, in winter do not forget about vitamin and mineral supplements.

The diet must be followed quite strictly to avoid obesity in birds. The amount of food should be standardized to eliminate the possibility of overeating. The productivity of laying hens will be highest in the case of three meals a day. At the same time, morning and evening feeding should consist of whole grains, and the day's - from wet mash. Also, for high egg production, you need to carefully monitor the balance of the diet; it must contain a sufficient amount of vitamins and minerals.

Breeding

First of all, the breeding process faces the problem of the reluctance of laying hens to hatch eggs. This instinct was almost completely lost by the breed in the process of selective work. Only one out of seven or eight hens can theoretically not only lay eggs, but also become a hen, although this statistic is not a guarantee. Therefore, you can’t do without an incubator. There are two more features that do not at all make it easier to try to increase the population.

When talking about breeding, the age-old question “chicken or the egg” is answered unequivocally by experienced farmers - chicken. It is with the purchase of adult birds that the process needs to begin. Purchasing eggs for their subsequent development in an incubator risks the fact that upon hatching, the breed may not be what was expected. Blue coloration of eggs can be inherited during interbreed matings, so they cannot be distinguished from purebreds by their appearance.

Small chicks are also not worth buying. At least because until the age of three months, females are practically indistinguishable from males. Therefore, you should wait at least 12 weeks. At this time, the cockerels begin to develop braids on their necks, and due to this, it becomes easier to determine the sex.

From young birds It is not advisable to start a family right away. After the first molt, the beard and tufts of both sexes may change or disappear. And as mentioned above, it is the presence of one of these factors in each of the parents that is practically a guarantee of a successful litter.

Araucana birds are also good for interbreeding. As a result, you can get strong offspring and colored eggs. For example, when crossed with a Russian Crested, the resulting chickens are unpretentious. The eggs are blue, like those of the Araucana. You can also get an olive-greenish shell color. This is done by crossing with hens that lay brown eggs. The resulting chickens are usually larger than Araucana chickens.

Acquisition

Since the breed is not very common, it is not so easy to find purebred representatives. First of all, you need to pay attention to the reputation and experience of the breeder, so as not to end up with a completely different breed. There are only three main points of sale in Russia:

On average, prices vary from 250 rubles. for chickens one day old up to 1200 rub. for birds that are already a month old. In any case, it is better to spend some effort and money to accurately obtain purebred Araucana chickens, and not their imitation. Purebred birds They will delight you with both productivity and undemanding conditions.

This is what Araucana looks like - a chicken laying blue eggs

If you ask any person what color chicken eggs are, he will answer: white or brown. But there are chickens that lay blue eggs. This Araucana chickens, which were brought to Europe in the 18th century from South America. The turquoise hue of the eggs is not the only feature of the breed: Araucana birds have characteristic feathery appendages in the ear area, and the German Araucana subspecies lacks a tail. The plumage of these birds is golden, black, light gray, white, black.

Composition of blue eggs

Despite the unusual color, blue chicken eggs do not differ in composition from their white “brothers”. They are rich in quickly digestible protein leucine, essential amino acids, vitamins B, A, E, and many beneficial microelements: potassium, iodine, selenium, zinc, magnesium, necessary for the heart, etc. But you shouldn’t abuse them - this product contains cholesterol.

What do blue chicken eggs look like?

It is enough for an adult to eat 1-2 eggs 3-4 times a week, for a child under 5 years old - 1 egg 2 times a week. Eggs are introduced into the diet of young children from about nine months of age. It is important to boil eggs until hard-boiled - blue eggs are susceptible to salmonellosis, just like regular eggs.

How to cook blue eggs

The taste of blue eggs is the same as that of ordinary white eggs, and from them you can make dishes familiar to many, such as hard-boiled eggs, fried eggs, and omelettes. If you want to prepare a gourmet dish, you can make a French breakfast - poached eggs. They are cooked without the shell: a “whirlpool” is made in boiling water, into which the yolk and white are poured, after which the egg is boiled until cooked.

Blue eggs are a beautiful natural phenomenon, great for those who prefer unusual and healthy dishes.

Ameraucana is a famous breed of chickens that lay blue eggs. In fact, two more interesting breeds of laying hens lay eggs with similar light blue shells - Araucana and Easter hens. But the heroine of this article is the delightful Ameraucana.

Description of the breed

Ameraucana chickens lay eggs in various shades of blue. It is believed that if a laying hen produces eggs with greenish or pink shells, then this is not a purebred Ameraucana, but Easter chickens, which are very similar in appearance.

Egg production is average - laying hens lay about 150 large eggs per year weighing about 60 g. Pullets begin laying eggs somewhat later than highly productive egg breeds; egg laying begins at the age of 6.5-7 months.

The breed has good meat qualities. An adult chicken weighs 2.2-2.5 kg, a rooster weighs 2.9-3.2 kg. Both roosters and hens form a marketable round carcass with tender white meat by the age of about 5 months.

The breed is also presented in a dwarf version - bantam hens weigh on average 750 g, cockerels - about 850 g. Like other bantams, the small form of Ameraucana chickens has a well-developed brooding instinct.

Appearance of chickens

The magnificent decoration of the breed is chic sideburns and a lush, clearly visible beard made of feathers. These expressive differences are inherent in both roosters and hens. The tail of roosters is of medium length, located at an angle of 45°, long braids are graceful, curved in an arc.

The comb is small, nut-shaped, and the earrings are almost invisible, which is a huge advantage for keeping this bird in cold regions. The comb, earrings and beard are red. Eyes – cherry or brown. The legs are the color of dark slate, the black variation is closer to a rich black tone.

The Ameraucana breed comes in a variety of attractive colors. The most common are black, blue, blue wheat, brown-red, buff (dark yellow) silver, wheat, lavender and white.

Breed Temperament

Fans note the unstable temperament of the breed - character and behavior are individual and vary from individual to individual. Some chickens are easygoing, inquisitive and prone to communication. Others are overly aggressive and eccentric. Some may be skittish, timid and not make contact with people.

And yet, in most cases, Ameraucana hens and roosters are calm and peaceful towards each other within their flock, and are quite tolerant of other birds.

Ameraucana rooster and hens

Resistant to cold, this unpretentious breed tolerates being kept in the limited space of a barn well. However, like most egg-laying chickens, Ameraucanas love to graze on range and are excellent foragers, significantly increasing productivity in the warm season.

During periods of increased egg laying, more calcium and protein are added to the chickens' diet, including legumes or protein-containing feed.

Ameraucana roosters can be aggressive; such individuals are kept separately from the main flock, only allowed in for breeding purposes. Like other breeds, this bird will thrive in clean barns with free range and constant access to fresh water.

Ameraucana chickens are not very willing to sit on eggs, but out of a dozen adult birds, several may well begin to cluck. It is advisable to transfer such hens to another barn, otherwise the rest may become interested in what is happening and, in turn, reduce egg production, and in the future want to hatch chickens.

Advantages and disadvantages of the Ameraucana breed:

History of the breed

The event that marked the beginning of the recognition of the Amerakuana breed occurred in 1976. Until this point, there were two versions of the Chilean Araucana chicken breed that lay blue eggs - tailless birds with whiskers and bearded birds with tails.

In 1976, a kind of lobby was formed on the board of the American Poultry Association (APA) and the first form without a tail and with lush sideburns became a real Araucana and received a standard.

Immediately, the breeders of the second form named their chickens Ameraucana (American Araucana) and began to develop and stabilize the breed. Four years later, in 1980, the breed received its American standard.

If golden eggs only exist in fairy tales, then blue eggs in chickens are a very real phenomenon. However, chickens have not only blue eggs, there are also green, and motley, and more familiar to us - brown and white. What determines such a diverse range of colors of chicken eggs and how to determine their color in advance? Let's look at this issue in this article.

First of all, the color of chicken eggs depends on the breed of chickens. So, there are several breeds of chickens that lay blue and greenish eggs. For example, Marans and Araucana. If you have chickens of these breeds in your yard, then you are guaranteed blue and green eggs. However, it is no less interesting when in one nest, along with blue and green, you find brown, pink, and white. And this is truly a beautiful sight!

Why do chicken eggs come in different colors?

Most eggs are initially white while the encased yolk passes down the oviduct, and they acquire their final color, corresponding to the genetics of the chicken, directly in the uterus of the chicken. So chickens of the Ameraucana and Araucana breeds lay blue eggs. As you can see in the photo, they look quite exotic and very cute.

These breeds have in their genes the presence of the pigment oocyanin, which colors the shell of their eggs blue; the pigment penetrates the egg when it passes through the oviduct.

Unlike other pigments, oocyanin colors eggs during shell formation. This causes the shell to be blue on both the outside and inside of the egg.

In chickens of the olive Egger and Easter Egger breeds, there is also a brown pigment - protoporphyrin, which, when superimposed on the blue shell, leads to the formation of green eggs with a blue inner surface of the shell.

Brown eggs are produced by the pigment protoporphyrin, but it acts on the shell much later in the shell formation process than oocyanin, so the inner shell of brown eggs remains white.

Chickens have colorful eggs

What color the eggs will be is determined by the breed of your chicken, whether they are brown, white, green, etc., is determined by the genetics of the chickens, which means the birds contain various pigments in their bodies. For example, eggs remain white if the breed does not contain any pigment.

Chickens, like humans, are born with millions of eggs in their ovaries, but only a fraction of them are laid during the chicken's life. After the mature egg is released into the oviduct, it matures in it for about 26 hours and most of this time is spent on the formation of the eggshell. It is only in the last few hours before the egg is laid that the pigment penetrates the shell, creating the different colored eggs.

Interesting advice- to determine what color the eggs will be, you need to look at the chicken’s earlobes. Generally, a hen with white earlobes will produce white eggs, while a hen with red earlobes will produce brown or multi-colored eggs.

What breeds of chickens lay colored eggs?

Here are a few food chickens that lay colored eggs:

• Maran- dark chocolate
• Easter Eggers- green, blue or pink
• Olive Eggers(somewhere between brown and blue) dark green
• Araucanas- blue
• Ameraucanas- blue (Ameraucana and Araucana are considered an identical breed; true Araucana are descendants of chickens imported from Chile to America in the 1920s).

Speckled eggs

While these eggs are usually completely normal, they may also look unusual, which may indicate that something is wrong with your egg. Sometimes it may be, or she may be experiencing some kind of stress, such as suffering from heat. But no matter what, speckled eggs are usually normal and quite beautiful.

Taste qualities of colorful eggs

Does the color of eggs affect their taste? Definitely no. Although brown eggs are more popular in grocery stores because they perceived, as more nutritious, in fact, the different colors of eggs have nothing to do with this belief.

Different colored eggs, like white ones, have the same amount of cholesterol, and their taste and nutritional qualities depend directly on how they are added to the basic diet.

So when eating these blue and colorful eggs, you don't have to worry about whether some of them are more or less nutritious than others.
