Different birds have different colors of eggshells, what exactly determines the color of eggshells?

Yellow eggs are not necessarily more "natural", and white eggs are not bleached. On the contrary, they are born like that, including blue-green eggs. But regardless of the color of the eggshells, they are all the same on the inside.

So why is it that everyone is born to a hen, but the "skin color" is different?

Professor Justin Fowler of the University of Georgia specializes in poultry science. He said"The eggs are different in color, or some are spotted, which is caused by different genes of the hens. ”

Laiheng chickens are the main commercial laying hens in the United States, and they lay white eggs; The eggs laid by Orpington and Rock Chicken are yellow; Ameraucana chickens produce a pigment that penetrates the entire eggshell, turning it blue inside and out. ”

If you want to know what color eggs a chicken lays, you can look at the color of its earlobes (yes, chickens have earlobes too!). "Chickens with white earlobes don't usually produce pigment when they lay eggs, so the eggs they lay are usually white. "In general, chickens with lighter earlobes have white feathers and lay white eggs, while chickens with colored feathers lay colored eggs.

How did these colors come about? This starts with the formation process of eggs。The hen's ovaries are the first to give birth to the yolk (also known as the egg).

The mature egg leaves the ovaries and travels to the fallopian tubes. In the fallopian tubes, the egg passes through five parts in order before going outside; The fourth part of this is the eggshell gland, where the eggshell is formed, and this part affects the color of the egg.

"All eggshells are made up of calcium carbonate, which is a white crystal. So all eggs are at least initially white. Colored eggshells are stained as they pass through the fallopian tubes.

If you don't believe it, you can crack open a coffee-colored egg and look at the color on the inside of the eggshell, and it must be white. ”

There are two main pigments that determine the color of eggs. Biliverdin causes eggs to turn blue or green, while protoporphyrins stain eggs yellow. The same is true for the eggshell color of other birds.

For example, the eggs laid by the American robin are blue, while the eggs of the murres are not only blue, but often have spots or brown stripes.

It is determined by the chromosomes of the genes, and the color of the eggshell will be different for different genes.

There are two main pigments that determine the color of eggs. Biliverdin causes eggs to turn blue or green, while protoporphyrins stain eggs brown.

The eggshell color of different birds is determined by the genes of the bird and the species of the bird.

The color of the eggshell is related to its genetics.

The color of the eggshell is determined by genes, the genes that determine the color of the eggshell.

It is the genes of the bird that determine the color of the offspring, which is said to give birth to nine different sons of a dragon.

This must be determined by the genes of the birds and the body structure of the birds.

The color of the eggshell is due to a combination of many factors, mainly to survive better.

Eggshell color can also vary greatly, as the ability to synthesize protoporphyrins varies from individual to individual.

We all know that birds are avid reptiles made of egg food, and their young birds are also grown and developed in the eggs of small birds, and they break out of the shell with all their might, I don't know if you have noticed, the size of the eggs laid by different birds also has different colors of their eggshells, <>

Just as the eggshell color of the eggs laid by the young pigeon is milky white, and the eggshell color of the eggs produced by the turtledove is not pure black or dark gray, but the color of the messy color, so it is all birds, the size is similar, and the nutritional elements are similar, why should the color of the eggshell be different? There are various reasons for harming the color of birds' eggshells, and different reasons are caused by the difference in the color of birds' eggshells.

First of all, it is the genetic elements that everyone understands, I think everyone understands that half of the genetic information of the fertilized egg cell comes from the father and the other half comes from the mother, so the sperm-egg combination will cause different practical effects after receiving the arbitrary matching of the genetic information of the father and the mother.

As the old saying goes, "a mother gives birth to nine sons, and each child is different", which indicates that different DNA compositions will cause different practical effects, and the color of the eggshell is precisely this kind of reason, although most of the eggshell colors of the same type of birds are similar, but if you look closely, in fact, the color of each eggshell has its own characteristics. It can now be seen that the color of the eggshell is partly determined by genetic inheritance.

At the same time, the color of the eggshell is also related to the environmental elements, for example, the eggshell color of the turtle dove is black and accompanied by many gray-black spots, this color can live in harmony with the surrounding natural environment, so it can reasonably avoid the discovery of nemesis, and then can ensure the survival rate of this type of bird, at this time, the eggshell can maintain the successful growth and development of a part of the internal IVF embryo at the same time, it can also ensure the safety of the young bird in the growth and development of the link, so no matter what, The eggshell color of the birds Mengniu Dairy ensures the natural and reliable growth and development of the birds.

The color of the eggshell of different birds is different, and the composition of the eggshell is a calcium carbonate. Most of the eggs are white, and some are cyan.

It will be affected by diseases, and it has a great relationship with the environment in which the eggs are laid, and it will also be affected by genetic factors, and it is also related to the external environment.

It is related to genetic factors, but it is also affected by the spawning environment, and it can be affected by diseases or breeds.

It is determined according to the species of birds, genetic factors, and of course some are caused by human factors.

We all know that birds are flying animals hatched from eggs, and their young birds are also growing up in bird eggs, struggling to break out of the shell, I don't know if you have noticed, the size of the eggs laid by different birds and the color of their eggshells are different, just like the eggshell color of pigeon eggs laid by pigeons is white, and the eggshell color of quail eggs laid by turtledoves is not simply black or gray, but chaotic color, so they are also birds, and the size is almost the same, The nutrients are all about the same, why is the color of the eggshell different? There are many reasons that affect the color of birds' eggshells, and different reasons can lead to differences in the color of birds' eggshells.

First of all, it is the genetic factors that we are familiar with, I think everyone knows that half of the genetic material of a fertilized egg comes from the father and the other half comes from the mother, so the fertilized egg will have a different effect after receiving the random pairing of the genetic material of the father and the mother.

As the saying goes, "a mother gives birth to nine sons, and the nine sons are different", which shows that different genetic combinations will have different effects, and the color of the eggshell is exactly the reason, although the eggshell color of the same species of birds is basically the same, but if you look closely, in fact, the color of each eggshell has its own characteristics. From here, it can be seen that the color of the eggshell is partly determined by genetics.

At the same time, the color of the eggshell is also related to environmental factors, for example, the eggshell color of the turtle dove is black and accompanied by a lot of gray-black spots, this color can live in harmony with the surrounding environment, so it can effectively prevent the discovery of natural enemies, so as to ensure the survival rate of the species of birds, at this time, the eggshell can protect the successful development of the internal embryonic part at the same time, but also to ensure the safety of the young birds in the process of development, so anyway, The eggshell color of the birds ensures the natural and safe growth of the birds.

It is mainly determined by the breed of birds, such as goose eggs are quite different from eggs, and secondly, it is related to the diet, health status, age and so on of birds.

Determined by the bird's genes, the different colors of the eggshell are dyed as they pass through the oviducts.

The color of the bird's shell is determined by the gene chromosomes, which determine the synthesis of substances such as bile pigments, which control the color of the bird's shell.

The eggshells of starlings, thrushes, brown-headed jays, etc., are pale green. 1. Starling eggs are blue-green, and shiny, the reproductive period of starlings is 4-8 months, sexually knotted, often standing on the back of buffaloes, or gathering on big trees, staying overnight in bamboo forests, big trees or reeds. 2. Thrush eggs are usually oval in shape and are sapphire blue-green or jade-blue.

Thrush is a special product of our country, its breeding history is long, all over the country has accumulated rich experience, eating miscellaneous, but more insects. <

The eggshells of starlings, thrushes, brown-headed jays, etc., are pale green.

1. Starling eggs are blue-green, and shiny, the reproductive period of starlings is 4-8 months, sexually married, often standing on the back of buffaloes, or gathering on big trees, staying overnight in bamboo forests, big trees or reeds, and inhabiting in groups with other starlings.

2. Thrush eggs are usually oval in shape and are sapphire blue-green or jade-blue. Thrush is a special product of our country, its breeding history is long, all over the country has accumulated rich experience, eating miscellaneous, but more insects.

3. The eggs of the brown-headed jay are white or light green or bright blue or blue-green, smooth and spotless, and the eggs are oval, oblong or broadly oval. Brown-headed jays usually nest on shrubs or bamboo bushes, but also on small trees such as tea trees and citrus, and the nest distance is in meters. The nest is cup-shaped and is mainly composed of grass stems, grass blades and other materials.

Chickadee egg belongs to the class of vertebrates, birds, and is a common name for various classes of the family (paridae). Small songbirds. Arboreal, staple food insects and their larvae, for agriculture and forestry birds.

1] It is commonly found in plains, hills, basins, etc., and the number in mountainous forest areas is still more than that in plain areas. The feathers of the chickadees are mostly gray-brown and brownish-gray, and although the difference between their calls is very significant, they all have a "boy black" scale, which is easy to distinguish. Nest in tree cavities or house holes, and almost all day long in the forest to feed on insects, and most of them are pests, so they have become the object of agriculture and forestry, and the attraction work that has been carried out at home and abroad has achieved remarkable results.

There are many species of chickadees in China, and most of them are resident birds. The most common of these are the great (Parus Major) and the swamp (Parus palustris).

This one is Magpie Egg.

Also called magpie eggs, magpie seeds, are the eggs laid by female magpies. It has a hard shell on the outside, and air cells, egg whites and yolks inside, which are rich in various nutrients. If the magpie eggs are fertilized, the baby magpies will hatch after about 21 days.

1. The green eggshell is a thrush egg. Lay 2 nests of eggs per year, 3-5 eggs per nest. The eggs are usually oval in shape and have a sapphire blue-green or jade-blue color.

Thrushes belong to the passerine order, the flycatcher family, and the thrush subfamily. It is widely found in eastern Gansu, southern Shaanxi, Hubei, Anhui, Jiangsu, and east of Sichuan and Yunnan in mainland China, Taiwan, and Hainan Island.

2. Inhabit hills and shrubs near villages or in shrubs, bamboo forests or courtyards on the outskirts of cities. I like to live alone, and I gather in small groups in autumn and winter. Sexually alert, timid, and hidden.

Standing treetops and branches between the branches, leading the neck to sing, the rhyme is changeable, euphemistic and beautiful, but also good at imitating other bird songs, animal calls and insect songs, especially in February to July, like to sing in the evening.
