The first stage of hatching isn't obvious. That's when the chick
breaks through the air cell in the large end of the egg and begins
to breathe and make sounds. The next stage
happens after the chick chips away at the inside of the egg, finally
breaking through the shell. The break is a small star-shaped crack called
a "star pip." It takes so much energy for the chick to make the
star pip that he usually will rest for at least 24 hours before beginning
the next stage of hatching.
