The hatching process begins days before you can see the chick. First, they make a hole through the internal shell membrane into the air chamber. The first signal to identify this is a small hole that is star-shaped, of 1/8 inches from side to side. At this point, it is necessary to adjust the humidity from 65% to 80% and wait. If you listen carefully, you will hear taps (like rhythmic sounds). The egg will start having a small crack and in 12 or 16 hours the sounds will be stronger. After 24 hours, during which the small hole does not become too large, you may hear a faint chirping. This indicates that the lungs are working, and the chick is breathing.

After a few hours, the chick makes a line of small holes which will eventually form a circle on the shell. This can take 24 hours approximately.

If it goes well, you do not need help; meaning that we do not have to break the shell and extract the chick. If we help the chick prematurely, the risk is that the yolk has not been reabsorbed, resulting in the death of the chick. It is preferable that the chick has to do a hard and long work to have a healthy birth and absorb the yolk sac.

The reflection that takes the chick to get pecking at the shell comes from a lack of oxygen and excess of carbon dioxide inside the egg. Hence, you should not break the shell prematurely. If pecking does not occur, a weak chick gives birth.

From day 18 of incubation, eggs should not be turned, being able to see from day 19 and 20 eggs chopped and staring the birth of the chicks.
