Eggs Introduction:

Eggs contain more protein, will increase the burden on the stomach and intestines. The highest content of protein in eggs, protein is easily denatured by heat. Eggs, also known as chicken eggs and chicken seeds, are eggs laid by hens.

Eggs have a blunt end and a slightly pointed end. The presence of air chambers at the blunt end causes the center of gravity of the egg to shift towards the smaller end. Because of the shape and center of gravity, when the egg is laid flat, the yolk always tends to the pointed end, and if it rolls, it will roll in a circle without rolling far, and when it rolls, it is always the big head that is out, so if there is a small damage, it will not affect the whole egg. If the air chamber is not at the blunt end, the egg will become a "tumbler", not conducive to the protection of the embryo and hatching.

The blunt end of the air chamber, when the chick is about to hatch, its head is often facing here, and then its mouth into the air chamber, you can breathe directly into the air chamber.

The shape of the egg is closely related to the shape of the chick in the egg. The tip of the egg is the very point of support for the chick's two feet, acting as a strong support, so the initial pecking open of the shell tends to favor the blunt end.
