The part of the egg that the chicken hatches into

Looking at the egg yolk in front of the light, the one with flocculent foreign matter is the fertilized egg, which can be used by hatching chickens. Eggs are not yolks and whites, they are fertilized eggs in the yolk. Not every egg will do.

The yolk of the egg will develop into a chick. At the tip of the yolk there is an embryo, from which the chick develops.

Come. Egg yolk is rich in fat and protein, which can provide the nutrients needed for the developing embryo. Egg white has the effect of protecting the yolk. The eggshell can protect the egg from external damage, and there are many pores on the eggshell, which can allow oxygen and carbon dioxide.

and water vapor through it, allowing the unborn chicks to breathe.

The development and hatching process of eggs.

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 to 19 days are the embryo growth stage, and the 20 to 21 days the embryo is fully grown, and the chick breaks out of the shell.

Two or three days before hatching, the chick will make a soft noise in the egg, and the hen will "coo" in response. When the chicks are about to emerge, the "talk" between the hen and the chick often lasts for several hours. This is when the hen is using the different calls of the chicks in the eggshell to understand whether they need to be hot or cold, so that the chicks can break out of the shell at almost the same time.

In chicken farms that do not hatch hens, chicks emerge one after another for two to three days.

Chicks are born. Mother chicken lays two eggs. It carefully placed the egg under its belly and hatched it carefully.

It's so warm in the eggs, and the chicks are growing up day by day, and they want to figure it out. Tuk, the shell is broken, and when the chicks see the blue sky, they think, it must be blue outside. Tuk tuk, the shell was broken, the two baby chickens purred, turned over, the chicks saw the red flowers, they thought, the outside must be red Qihe.

When the chickens came to the meadow and saw the green trees, red flowers, and blue sky, they said happily, "It is colored outside!" "The two chicks grew bigger and bigger, and slowly became a little rooster and a little hen.

They grew and grew and grew and became chicken fathers and chicken mothers, and took the baby chickens to the grass to learn their skills.

Scientific: Chickens hatch from eggs.

Extend and extend. In every corner of our lives, questions are almost everywhere, and these silly questions can often stimulate children's precious curiosity, which can lead children to correctly understand and understand the world, and further explore the mysteries of the world, which is the most critical part of early education. File letters.

In order to let the children better grasp the pulse of the times and be the literati of knowledge, we hereby compiled this "Science Story", which really caters to the psychology of children, covering a wide range of content, vivid and vivid plots, invisibly cracking the mystery in the hearts of children, and this book is the best extracurricular reading material for children. (Excerpt from Encyclopedia).

The placenta, which contains the nucleus, is the part of the embryo's development, so the chick is developed from the embryonic segment in the egg.

The hatching chicks are small, delicate, short fluff, low heat preservation ability, and the function of regulating body temperature is not perfect, until 3 or 4 weeks old, it is gradually complete. Therefore, doing a good job of cold protection and heat preservation, adjusting the appropriate temperature and humidity is the key to raising chicks well and improving the survival rate of chicks.

The suitable temperature for chicks is: 30 32. Later, every 5 days to cool down 1 2, after a month of age, if the outside temperature is above 20, you can naturally give Wen Jinyin, otherwise you should continue to keep warm.
