Day 20

700



We have an internal pip!

The chick has pierced the internal membrane and pipped into the air cell. It is now breathing air. Some gas exchange can happen through the egg shell, which is porous, giving the chick time to finish absorbing the vitellus. Vitellus absorption (usually) is completed on this day. External pipping may also occur.
