Chickens have a varied diet. They eat insects, worms, fruit,
seeds, acorns, slugs, and snails. They have a well developed
gizzard (a part of the stomach that contains tiny stones) that
grinds up their food.

The Formation of an Egg The yolk: The chicken egg starts as an
egg yolk inside an hen. A yolk is produced by the hens ovary in a
process called ovulation. Fertilization: The yolk is released into
the oviduct, where it can be fertilized internally. The Egg White:
The yolk continues down the oviduct and is covered with a membrane,
structural fibers, and layers of the egg white. This part of the
oviduct is called the magnus. The Eggshell: The eggshell is
deposited around the egg in the lower part of the oviduct of the
hen, just before it is laid. The shell is made of calcite, a
crystalline form of calcium carbonate. The entire trip through the
oviduct takes about one day. The Incubation Period: The embryo
develops inside the egg for 21 days, until the chick pecks its way
out of its shell egg shell and is hatched.
