Vitellus fully resorbed; closing of the umbilicus.
Vitellus fully resorbed; closing of the umbilicus. The chick pierces the inner shell membrane and breathes in the air cell. Gas exchanges occur through the shell, which is porous. The chick is ready to hatch. Piercing of the shell begins. GURRAM SRINIVAS

The chick uses its wing as a guide and its legs to turn around and pierce the shell in a circular way by means of its egg-tooth. It extricates itself from the shell in 12 to 18 hours and lets its down dry off. GURRAM SRINIVAS
