How can chicks hatch without eggshells? Can you talk about it?

Do you know how chickens hatch? Do you think eggs without eggshells can hatch chickens? Carefully take out the eggshell and pour it into a special incubator. Pour calcium lactate into plastic wrap, add distilled water, then put it in a rubber band and hang it on the glass. The next step is the incubation process.

First of all, the vascular system of the embryo has formed a small circle with capillaries leading to the center of the yolk, and his little heart has begun to beat here, which is amazing. The capillaries are more and more abundant, and the heart and main blood vessels are wrapped in a transparent embryo. This embryo is very small, especially his heart, only about a millimeter, but magically, such a small heart can already transport the blood needed by the body. We can clearly see the outline, eyes, even wings and legs of the chicken. The yolk broke and spread to the whole surface of the egg liquid. The chick's embryo began to move for the first time, and the color of its eyes was obviously black. A transparent liquid bubble is formed around the embryo, and a small embryo floats in it. This blister has a certain protective effect. The chick embryos inside move more and more frequently. A large number of blood vessels and capillaries constantly transport nutrients from egg yolk to embryos, and they can absorb more and more nutrients from egg yolk. The chicken's shape is becoming clearer and clearer, and its eyes are more obvious, and even its wings and feet can be clearly seen.

Then, the chicken's eyes opened and kept turning, and its wings became clearer and more energetic. In just two days, feathers have begun to appear on chickens, especially on their tails and sides. The blood vessels on the membrane are getting thicker and thicker, and its claws are stronger. I wonder if it will break this fragile membrane. Chickens have ears, and this ear can only be seen at this time. In a few days, when the feathers are rich, they will hide. The chicken's body is covered with feathers, and it begins to breathe the air of nature. Oxygen will permeate from the eggshell, then enter the blood and be transported to the chicken. But it didn't hatch. Chickens need to drill a hole in the cup, insert a hose and enter a special incubator. The chicken has almost absorbed the nutrition in the yolk, and the whole space is occupied by its body. The chicken is well developed, just wait for it to hatch.

Finally, chicks usually break their shells on the second1day, but some malnourished chicks may not have a chance to eat. On the second day1day, the chicken successfully broke the egg liquid film covering it without breaking the eggshell. But the newborn chicken is very weak and needs to be given a proper temperature to keep its body warm.
