Oviparous animals. Eggs from different animals have different shapes and sizes, but each egg has a similar composition, with a fragile shell that protects the yolk and white. As the hen ovulates, the yolk is released, which can then be fertilized and continue through the hen's reproductive tract.
Egg whites are made up of a variety of different albumin layers, structural fibers, and membranes that surround the yolk as it passes through. Finally, the eggs are usually shelled and laid by the hen within 24 hours.
The fertilized yolk contains all the genetic information needed to create a newborn chick.
To support the development of chicks, eggs are rich in fat and protein, and the more fat in the yolk, the darker its color will be. Have you ever wondered how unborn chicks breathe inside their shells, every animal needs oxygen to survive, so chicks have to breathe air somehow to survive in eggshells. When an animal inhales, oxygen enters the lungs and is then distributed to different parts of the body, converting oxygen into energy through the animal's metabolism.
In this process, animals produce a substance called carbon dioxide.
exhaust gases. To expel it, carbon dioxide is brought back to the lungs, where it is collected and exhaled. Therefore, the chicks must not only find a way to get oxygen in, but also some way to get the carbon dioxide out.
Birds and reptiles.
The eggshell is hard, with two membranes just below the shell, and between the membranes is a small oxygen-filled air sac that automatically replenishes oxygen and releases carbon dioxide as the animal develops. If you use a magnifying glass.
Inspect the eggs carefully and you will see the shells.
There are many small holes on it, which are called holes. When the mother lays the eggs, those two membranes just below the shell are warmer than the air, and when they cool, the substances inside the eggs shrink a little. This contraction separates the two membranes, leaving small oxygen-filled air sacs.
When a chick is hatched, its heart will grow first, forming a small beating red dot inside the egg, and then it will slowly form the shape of a chick, absorbing the nutrients in the yolk, and when the chick is not yet mature, it will have a similar umbilical cord in front of its belly.
The same thing connects it tightly to the yolk. After that, the yolk slowly becomes smaller until it is completely gone, as the nutrients inside have been absorbed by the chicks. After that, the cracking stage is the stage where the chicks use their beaks to peck a small hole in the eggshell, and then struggle to get out of the eggshell, and those who do not come out may suffocate to death in the eggshell.
-
First, the chick will slowly form a prototype, then gradually begin to grow feathers, and at the same time, the muscles around the chick's mouth will develop, and when the chick is fully grown, it will use its beak to break out of the shell.
-
Chicks rely on the protein and cholesterol in their eggshells to get the nutrients they need. Chicks have a heartbeat, then slowly grow other organs, and finally develop feathers.
-
Chicks rely on the protein and cholesterol in the eggshell to get the nutrients they need, and then slowly grow up and eventually break out of the shell.
-
1. The humidity of incubation in the later stage is too small, and the water loss ratio of eggs increases.
2. The eggshell is too thick, and the chicks are powerless to peck open the eggshell.
3. Dislocation, under normal circumstances, the head of the chick is in the direction of the air chamber, but there are also inverted births, and later suffocation death.
4. The eggs themselves carry pathogens, which belong to vertical transmission, resulting in the later death of chicken embryos.
5. Turning the egg with too much force will cause the air chamber to drift or misalignment.
6. In the later stage, excessive urine nitrogen production will cause self-poisoning and death.
-
The process of turning eggs into chicks is mainly for the hen to lay eggs and then hatch the eggs through body temperature, so that the chicks can be born smoothly.
-
The egg is hatched by the mother chick and is a long process that first becomes a fertilized egg, then slowly grows up, and then becomes a chicken.
-
After 21 days of incubation through the incubator or nest hens, the chicks emerge from their shells. Eggs are fertilized, chicks hatch, and new life is born.
-
Summary. No, the eggs of chicks do not stand up. Normally, eggs are hatched in a natural equilibrium state, so they do not stand up. If they need to stand up, they need to be supported with special equipment or stands.

The eggs of chicks are usually in a state of incubation. At this stage, the chick's shell is broken, the chick begins to emerge from the egg, and begins to prepare to enter the world. It is not certain whether the eggs of the chicks are erect.
-
The chick moves until the shell is openedBecause the eggs are liquid at the beginning, there will be no gaps when shaking, so you can't feel the sound, and the eggs will have a sound when they are broken, but after the egg hatchery chicks, you can use a searchlight to see that there is a prototype of the chicks when they turn black.
Chicks are the young of chickens that hatch from eggs. Chicks eat feed and vegetables, insects, broken rice to grow, chickens are the most common poultry raised by human beings, domestic chickens are derived from wild chickens, and their domestication history is at least about 4,000 years, but it was not until around 1800 that chicken and eggs became mass-produced commodities.
Chick habits.
Poor cold resistance, the hatch chicks, the body temperature is 3 degrees Celsius lower than the adult chickens to reach normal body temperature after 10 days, plus the chicks fluff is short and thin, can not keep out the cold, so the adaptability to the environment is not strong, must rely on artificial insulation, chicks can grow and develop normally.
Chicks from 1 to 30 days old should be kept warm and kept in a clean and hygienic environment, and chicks over 30 days old have feathers that are basically full and long, and they can be kept warm without heat preservation.
Weak resistance, especially chicks, are easily attacked by harmful microorganisms, so in addition to cleaning and sanitation of the environment, it is also necessary to do a good job of prevention, such as the chicken coop is strictly forbidden for outsiders to enter and exit, the environment and cages should be disinfected, and all kinds of chickens should be regularly injected with various preventive injections.

An egg has three parts: yolk, egg white, and eggshell. At the tip of the yolk there is an embryo, from which the chick develops. Egg yolk is rich in fat and protein, which can provide the nutrients needed for the developing embryo.
Egg whites have the effect of protecting the yolk. The eggshell protects the egg from predators and has many pores that allow oxygen, carbon dioxide and water vapour to pass through and allow the chick to breathe. Under the right temperature, humidity and other conditions, the embryo will grow and develop.
The first 4 days are the internal organ development stage, the 5 14 days are the external organ formation stage, the 15 19 days are the embryo growth stage, and the 20 21 days are fully grown, and the chicks break out of the shell.
The whole process of turning an egg into a chick, illustrated with a picture:
This is an egg that is ready to be used to hatch chicks. (Figure 1).
A few days later, the surface of the yolk was bloodshot. (Figure 2).
The blood streaks gather and the yolk spreads. (Figure 3).
Eyes begin to appear. (Figure 4).
The eyes gradually get bigger. (Figure 5).
Form the outline of a chick. (Figure 6).
Thin feathers grow. (Figure 7).
It looks like a chicken. (Figure 8).
Further development. (Figure 9).
Finally turned into a cute chick. (Figure 10).

First of all, we need to know that the egg is the egg cell, where the real egg cell is the yolk, and the egg white is just the nutrients provided for the incubation process. This is exactly what the name of protein (a class of nutrients) is...Therefore, we say that chicks are all ,.. from the yolk (egg) of a fertilized egg
Also, when dissecting the hen, you can see the yolk of various sizes. These are the egg cells that are not yet fully developed. The shell of an egg is a calcareous hard shell, called an egg shell.
The eggshell plays a protective role. There are about 7,000 small pores in the egg shell, which can be ventilated, and there are two layers of egg membrane close to the egg shell, and the outer layer is thicker. Within the blunt end of the egg (the large head), a small air cell is often separated between the two membranes to store air for the embryo to breathe during development.
That's the hollow part of a hard-boiled egg). Inside the egg membrane is a large amount of egg white (egg white), which is composed of water, protein, a small amount of sugars and inorganic salts; The outer layer is thinner, which can be called dilute protein, and the inner layer is thick, which is called concentrated protein. These substances are nutrients for the development of the chicken embryo.
Further inside is a spherical yolk (yolk), which is the egg cell. There is a very thin membrane on the surface of the yolk, called the yolk membrane, which is the cell membrane. The yolk is generally stratified, composed of yellow yolk and white yolk arranged in concentric circles, with a yolk heart in the middle, connected to the yolk heart neck and the placenta, along the long axis of the egg, the two ends of the yolk are composed of thick protein yolk frenulum, which keeps the egg cell in the center of the protein, plays a buffering role, prevents the egg from being the first to hatch, and is conducive to the hatching of the egg.
The yolk has a small white disc (that is, the small white dot seen on the yolk), which is composed of the nucleus and a part of the cytoplasm, which is the placenta. In the case of fertilized eggs, the placenta can hatch chicks under the right conditions.

Answer hello, dear, in this case you can probably raise yo like this1The chicks that have just hatched are the period when they need to be carefully cared for, and they need to have a temperature of about 34-37 degrees for the chicks not to be crowded, not to be bunched, and to move freely. 2.
The temperature must not fluctuate too much, and too much fluctuation can easily cause some respiratory diseases in the chickens. Once you get sick, it will be very troublesome. 3.
If you raise chickens in a closed chicken coop, you must be full of gods. 4.Freshly bought chicks should never be placed directly in cement.
Earth. Above. Because the cement floor is too cold, the chicks are easy to loosen, and the survival rate will be greatly reduced in the future.
A layer of about 1 cm should be spread with dry sawdust, so that the chicks will be warm when stepping on the dry sawdust and will not catch a cold. 5.Use a bucket for feeding, and put a few more.
In this way, the feed is not easy to waste, and the chicks will not be trampled for food. 6.It is best to feed the chicks you just bought with warm boiled water, and don't bother to boil the water if you have many chicks, warm boiled water is the most beneficial to the chicks.
If he tells you not to feed water for three days, you should let the chicks adapt to the environment, so as not to have problems by changing the environment and food.
Question: So, dare to feed the chicks warm water?

The embryo in the yolk will develop into a chick in the future.
The embryo of a chick that has been developing for 4 days and resembles a spider.
The embryo of a chicken that has been developing for 5 days has the rudimentary shape of an eye.
The embryo is 6 days old and can see both eyes.
On the 7th day, it sinks into the yolk.
On the 8th day, embryonic embryonic forms and is motile.
In 9-10 days, the mouth and claws can be separated, and the blood vessels are thickened.
On day 11, feathers grow on the abdomen and the allantois closes.
At 12-13 days, the hair is long and the upper and lower jaws are distinct.
At 14 days, the feathers cover the entire embryo with very little protein.
At 15 days, the body grows and the head is stretched towards the big end.
16-18 days, the hair grows and the scales and claws appear.
For 21 days, the chick pecked at the eggshell, fluffy, very cute.
Cancer occurs in this way: cancer is a disease produced by the combined action of the genetic environment, and most cancers have been proven to be caused by exogenous carcinogenic factors and the body's own genetic aging, immune metabolism and other factors.
Snail noodles are a traditional ingredient in Liuzhou, Guangxi, it has special feelings for Liuzhou people, they would rather not eat meat, but not without snail noodles, it can be seen that the status of snail noodles in the hearts of people in Liuzhou is very high. But many people who have just eaten snail noodles smell it, like a smell of stinky feet, which makes many people unbearable. In fact, the "smell" in snail flour comes from sour bamboo shoots, which are pickled and produce a special flavor during the fermentation process. >>>More
