5. 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.

6. Many animals eat chickens including, skunks, owls, raccoons, hawks, snakes, and even people.

7. The Formation of an Egg  The yolk: The chicken egg starts as an egg yolk inside an hen. A yolk is produced by the hen’s 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.
