Hens can't lay eggs every day, and the hens currently specially bred for laying eggs lay eggs in about 280 eggs per year, and the egg is not the hen's "menstruation", but a huge egg cell, egg production and menstruation are different divine phenomena.
We all know that some eggs can hatch chicks, indicating that laying eggs is the way of reproduction of chickens, and eggs are the egg cells of chickens, which are used for reproduction, not just for laying eggs.
Chicken is also a kind of hermaphroditic creature, hens lay eggs on the same issue as why human beings want to reproduce, only in this way can the whole species population survive, although the chicken may not be aware of the significance of reproduction for the population, but physiologically can not carry out the reproduction behavior of the individual will basically be eliminated by nature, the corresponding genes will also disappear in the group, and gradually make the whole population of normal individuals will reproduce under the control of genes.
Although pheasants in the wild also lay eggs, but their egg-laying behavior is mainly for reproduction, their egg-laying rules are different from the laying hens cultivated by humans, two or three litters a year, a litter of several dozens, raising a group will be separated from the population to form a new small group, their egg-laying behavior is related to the environment and the breeding season, there will be a delay and a pause, there will be an advance, the time law is a bit like human menstruation.
But menstruation, although it is a phenomenon caused by ovulation of human women, mainly due to bleeding and other physiological reactions caused by endometrial shedding, is caused by changes in hormone levels in the body, but generally referred to menstruation is the period when menstrual blood flows out, and the eggs laid by chickens are not counted, eggs are just egg cells.
Hens in the artificial breeding environment, due to the special cultivation of human beings, so that the laying hens have a very high egg production rate, up to 300 a year, at the cost of their waking time is almost eating, laying eggs This matter is still quite large in energy consumption.

In nature, it is relatively rare for birds to produce unfertilized eggs, because they will find males in time to mate, fertilize egg cells, and ensure the reproduction of the race.
In modern layer farms, where roosters and hens are kept in separate pens, the eggs harvested every day are eggs that have not been inseminated by males.

The hen doesn't lay eggs every day, it just ovulates regularly, so it produces eggs.
-
The hen lays eggs in the same way that humans reproduce, but why does it lay eggs every day? It can only mean that it eats a lot, as long as there is food in the stomach, it will lay eggs, on the contrary, if it does not have to eat, it will definitely not lay eggs every day.

The chicken is also a hermaphroditic creature, and the question of hens laying eggs is the same as why humans should reproduce, only in this way can the whole species population survive, although the chicken may not be aware of the significance of reproduction for the population;
However, the individuals who are physiologically unable to perform reproductive behaviors will basically be eliminated by nature, and the corresponding genes will also disappear in the population, gradually making the normal individuals of the entire population reproduce under the control of genes.
Whenever an egg cell matures, whether it is fertilized or not, it inevitably enters the reproductive system, then is encapsulated by egg whites, which are egg whites, and then enters the uterus, where it forms an eggshell, and after forming a complete egg, it is finally excreted from the body.
Therefore, the egg cell of the chicken is maturing all the time, and each egg cell will inevitably grow into an egg. That's why chickens keep laying eggs.

Hens can be more bai
The high frequency of laying eggs is the result of artificial selection.
Chickens are the DAO's version of the human ancestors, who were domesticated from the wild to the poultry over time. In the process of domestication, it was discovered that eggs could be used as a good food, and more chicks could be hatched through eggs. Chickens with a high frequency of laying eggs are deliberately selected for a large number of breeding.
After a long period of artificial, many generations of this artificial selection, the chicken's ability to lay eggs frequently is strengthened and retained.

Chicken is also a hermaphroditic creature, hens lay eggs on the same issue as why human beings want to reproduce, only in this way can the whole species population survive, whenever an egg cell matures, regardless of whether it is fertilized or not, it will inevitably enter the reproductive system, and then be encased by egg white, that is, egg white, and then enter the uterus, and then form an eggshell, after forming a complete egg, and finally be excreted from the body, so the egg cells of chickens are maturing all the time, And each egg cell will inevitably grow into an egg.

What do you usually eat in the morning? Eggs are believed to be indispensable for everyone, and they are rich in protein. But have you ever paid attention to the fact that during the laying period, basically every hen can lay an egg every day.
In most wild birds, the number of eggs per nest is limited. Why? If you want to know, let's find out.
During the breeding season, the number of eggs laid by a wild bird in a nest is relatively fixed, and this number varies depending on the bird species, which is called the number of eggs in the nest. The number of eggs in the nest is gradually formed through long-term natural selection. Too few eggs laid by the parent bird will affect the transmission and dispersal of individual genes.
The parent bird lays too many eggs, which exceeds the ability of the parent bird to raise them. Therefore, under the combined action of various conditions such as environment and food, each bird has formed its own relatively stable nest egg count.
Although the number of eggs in a bird's nest is relatively stable, it is still divided into two categories: fixed and indefinite. When an indefinite number of birds, such as pheasants and swans, hatch, if one of the eggs in a nest is broken or eaten by other animals, the female will often lay another one, so that the number of eggs in the nest remains relatively constant. If one egg is taken from the pheasant's nest every day, the female will lay one more.
However, because egg laying consumes a lot of energy and nutrients, there are limits to the egg replenishment behavior of wild birds. Domestic chickens were domesticated from red junglefowl about 8,000 years ago, and their egg-laying habits are also indefinite. Since the hen can get enough nutrients under artificial feeding conditions, it is possible to induce the hen to keep laying eggs as long as it takes the eggs it lays every day after it begins to lay eggs.
This is the reason for the high production of hens.
Birds that lay a fixed number of eggs, such as golden eagles and brown-headed jays, lay only a fixed number of eggs at each breeding time and then begin to hatch. For example, the golden eagle usually produces 2 pieces, and the brown-headed jay usually produces 3 5 pieces. If one of the eggs in the nest breaks or eats, the parent birds of such birds will not replenish the eggs, but continue to hatch other eggs.
Editor's note: The hen crowing is also a spectacle. Delicate pen and ink, exquisite description, appreciation! >>>More
I think the purpose of the egg is to tell the hen that the egg is very safe to keep here, and that it can safely lay the egg in the nest. In general, when there is an egg, the hen will lay her own eggs in it.
Actually, I think the hens bask in the sun to attract the attention of the roosters. After marriage, the hen basks in the sun to support her husband's career, after all, the sun is made by the rooster crowing.
Of course it's hot, it's in the hen before it comes out, it's hot in the hen's body, and the egg is hot too.
