Why do hens don t need roosters to lay eggs? So what is the meaning of the existence of the rooster?

This is because the eggs laid by the hen are not fertilized eggs, so the eggs can be laid without a rooster, and the meaning of the existence of the rooster is to be able to reproduce, and the eggs laid by the hen themselves cannot hatch chicks.

This is because the rooster needs to mate with the hen, which lays the eggs through fertilized eggs. The reason for the existence of the rooster is to mate, to reproduce.

This is because the rooster needs to mate with the hen in order to fertilize the egg. The purpose of the rooster's existence is to reproduce.

The hen can lay eggs as soon as it ovulates, and the significance of the rooster is to pass on the lineage, and only fertilized eggs can hatch into chicks.

Although hens can lay eggs without mating with roosters, this kind of eggs can only be eaten, and chicks cannot hatch, and if this continues, chickens will gradually become extinct, so if you want to breed the next generation for a long time, roosters are necessary.

At that time, the rooster could also lay eggs, but he was afraid that his hens would be laid off.

Hens don't need roosters to lay eggs, but hens lay eggs that are oligopolis and can't hatch chicks. If no roosters exist, then the population of chickens in nature would be extinct. Hens will have offspring because of the presence of roosters.

This is also the same as humans, women can ovulate without men, but do not produce offspring. Women have men to produce offspring!

Raw eggs. It is the innate nature of hens, and it is also the unique physiological function of hens compared to roosters, which has nothing to do with whether there is a rooster or not.

In other words, as long as it is a hen, it should be born with the ability to lay eggs and lay eggs. Otherwise, it is not a qualified, functioning hen.

In this way, perhaps the subject will feel that the question he raised is indeed very correct and normal, and the rooster in the world really has no meaning of existence.

I think it's a special physiological phenomenon in birds. You see, all the birds that are females, not all males, without exception, can lay eggs.

Of course, the rooster has a meaning of existence, the hen is not inseminated by the rooster, and the eggs laid are infertile eggs and can only be eaten by people, it cannot hatch chicks. The rooster plays the role of reproduction, how can it be said that there is no meaning? It makes a lot of sense!

The matching of roosters and hens is generally according to a rooster, with eight to ten hens is enough, it can ensure that each hen lays eggs, fertile eggs can reach more than 90%, and there are also a small number of infertile eggs, commonly known as "oligopolized eggs".

Chickens are avian and oviparous animals.

The hen will lay eggs naturally. The role of the rooster is to inseminate the hen's eggs, and without the rooster insemination, the hen's eggs cannot hatch the chicks. If only human eggs could also develop into children outside the body, women would not have to bear the pain and danger of giving birth.

Chickens are oviparous, no oviparous animal does not need to mate, and the same is true for hens, female oviparous animals can undergo internal fertilization to lay eggs, but eggs that have not undergone fertilization cannot hatch chicks.

It is an instinct of a hen to lay eggs without a rooster, but this kind of egg is not fertilized, which means that it cannot hatch chicks. If it can be mated with a rooster, the eggs laid by the hen can hatch chicks.

This is because chickens are originally an oviparous animal, and usually laying eggs belongs to ovulation, so it has little to do with fertilization.

The hen does not need a rooster to lay eggs, but the eggs it lays cannot hatch chicks, and if there is no rooster to grow into a chicken in nature, it will be extinct, because of the existence of a rooster, there will be offspring of chickens, and in case of danger, the attack can also protect the hen to a certain extent.

Because the egg is not fertilized, there is no way for such an egg to hatch and give birth to chicks.

Because when the hen lays eggs, it can be salted into eggs through its own eggs and proteins; Roosters have the meaning of existence, and if there are roosters, then the eggs produced by the hens are fertilized eggs.

In fact, in life, it is not only the hen that has this function of ovulation on its own, because you will find that the women around you will also have this phenomenon (menstrual cycle). Although a woman's ovulation every month is very special, it is also a common characteristic with a hen. The reason why women have pain for so many days every month.

It is because the eggs in their bodies are expelled by themselves as the endometrium is shed without fertilization.

Therefore, for hens, they can lay eggs without roosters because they can achieve physiological regulation, which is what we call ovulation.

In the case of hens, their embryos develop in eggshells, but for us humans, the fetus of women develops in the womb. In fact, sometimes the eggs released by the hen can be enough for the hen to lay eggs for several days in a row. There is also the fact that the hen is in the egg laying cycle, in fact, the quality of the eggs is determined according to the breed of the chicken.

For example: "There are big and small, there are many and there are little!" "Other than that, the principle of laying eggs is the same for hens.

In addition, the hen's reproductive system is made up of two parts. One is the ovaries and the other is the fallopian tubes. The yolk that forms the egg develops in the hen's ovaries and is released from the ovaries to the hen's oviducts when the egg matures, resulting in ovulation.

As we mentioned at the beginning of this article, hens don't need roosters to ovulate and lay eggs. Just like the one analyzed aboveThe hen's eggs pass through these 5 parts in the oviduct: "yolk - egg white - soft membrane - eggshell - egg".This process has always been done by the hen herself, and has nothing to do with the rooster.

But the eggs that come out like this can only be called "Yunying eggs", that is, eggs that have not been fertilized, and such eggs cannot hatch chicks. However, the eggs that hatch chicks in real life are those that have been fertilized after mating with a rooster. So although hens are able to ovulate and lay eggs on their own, if there are no roosters in the world, then"Eggs are just eggs, and hens can lay eggs, but eggs can't give birth to chickens."

Therefore, the existence of the rooster is a physiological species set for the chickens to reproduce the next generation, so I think this is the meaning of the existence of the rooster.

In short, we only need to understand one truth, and the existence of anything has its value. Although it is said that a hen can ovulate and lay eggs without a rooster, can a hen lay eggs that can hatch chicks without a rooster? The answer is no!

Finally, here is a way to distinguish eggs, if we want to know whether the eggs on the market are Yunying eggs or fertilized eggs, then we only need to put this egg under the light to see it. The transparent ones are Yunying eggs, and the opaque ones are fertilized eggs!

Because hens do not need to mate and can complete single-sex incubation, the existence of roosters is particularly high, they can crow, they can hatch chicks smoothly, and they can protect the quality of life.

Because hens lay eggs by hatching them, there is no need for roosters and no need for mating. Roosters exist to maintain the balance of the ecosystem.

Because hens are able to lay eggs through in vitro fertilization, the role of the rooster is to provide us with food, because our human body needs the nutrition of chicken.

Without a rooster, a hen would lay eggs.

Eggs are divided into fertilized eggs and unfertilized eggs. There is basically no difference in appearance between fertilized eggs and unfertilized eggs, so most of the eggs that people usually eat are not fertilized by roosters.

The hen's egg-laying behavior is regulated by its own circadian rhythm and has little to do with the rooster. 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 that are harvested every day are those produced without male insemination. After an egg cell forms an "egg yolk", even the hen herself cannot guarantee that it will be fertilized.

However, if the hen successfully mates with the rooster before laying eggs, it will lay fertilized eggs, which can hatch chicks.

In the absence of a rooster, the hen lays eggs normally.

In the state of the natural environment, the rooster and the hen must mate in order to reproduce. Hens that lay eggs that are not "mated" to roosters will not hatch into the next generation. Adult hens ovulate every 25 hours or so, and the fertilized eggs are released from the body and are suspended if they do not reach the critical temperature for incubation24.

In captivity, to see if the egg is fertilized, you can shine the egg against the bulb, if there is a small shadow at one end of the egg (usually eat shell-boiled eggs and knock on the end with pores), it means that the egg has been fertilized, and if there is no shadow, it means that the egg is not fertilized and cannot hatch chicks.

That's an extreme question.

The answer is – of course Bai does

The reason is that the hen side zhi

The ovary degenerates on the other side of the ovary to produce mature eggs through the bell at the front end of the fallopian tube into the fallopian tube, the fertilization process occurs at the upper end of the fallopian tube (the eggs we eat are not fertilized), the fertilized egg is in the fallopian tube downward process, in turn by the fallopian tube wall secretion of protein, shell membrane and eggshell wrapping, the egg moves in the fallopian tube due to the movement of the tube wall muscle and rotates, wrapped in a protein layer, the two ends of the protein with twisting to form a frenulum, that is, we open the raw egg, found the egg yolk at both ends of the white band. The eggshell is 89% 97% calcium carbonate, with a small amount of salts and organic matter. Some eggs have colors and patterns that are produced by pigment cells in the lower end of the fallopian tube.

Yes, laying eggs by a hen is an act of ovulation, similar to a woman's menstruation. There are fertilized and non-fertilized eggs that are released. It's just that the human egg is fertilized and hatched in the uterus, while the chicken is expelled and hatched. Without a rooster, the eggs will not be fertilized, and the chicks cannot hatch! Adopt it.

There are no roosters, and hens have to lay eggs, but the eggs laid in this way do not produce chicks.

Yes, female mammals need and.

Male mammals can reproduce by mating, while birds can lay eggs without mating, so hens do not need to find roosters to mate before they can lay eggs.

However, if the hen does not mate with the rooster, the eggs laid are infertile eggs and cannot hatch chicks, but can only be eaten by humans.

Because there is no rooster, the eggs laid by the hen are inferential.

This one can't hatch chicks.

Bird reproduction is slightly different from that of mammals, although everyone is fertilized in vivo, but birds belong to in vitro development, and this special process is the same.

It is often referred to as hatching eggs. Females lay eggs during their gestation cycle, but this has little to do with males. Under normal circumstances, if the bird is not fertilized, the female will still lay eggs, but this bird egg is a single egg cell, and the yolk inside the hard-shell egg is called egg yolk.

When you eat boiled eggs, you will find that the egg yolk is dark brown on the outside, which is the cell membrane of the egg cell, the yolk membrane. Inside is the cytoplasm, the main part of the yolk. Attentive people can find a small scotoma on the surface of the egg yolk, which is where the genetic material is located, that is, the nucleus.

Yes, but not into chicks.

Yes, no rooster can lay eggs. However, this type of egg cannot hatch chicks because it is an unfertilized egg.
