Penguin chicks eat whatever their parents eat. This is because
the parents chew and swallow up food that they eat like fish or
krill, and then they usually regurgitate it into the mouth of the
chicks since its is easier for them to eat.
What do chicks eat and what do they like?
Chicks (as in baby chickens) will eat grain, insects, grass,
anything that they see their mother pecking at.
