Eggs Easier - Eggs are special cells found in female animals. Nearly all animals produce eggs. Some animals lay eggs outside their body. For example, birds lay oval, hard-shelled eggs. Harder - Oology is the study of eggs.
Many animals lay eggs in water, on leaves, or in nests.
These eggs have a covering that protects the developing creature. Turtles, lizards, birds, fish, reptiles, dinosaurs, insects, and some mammals lay eggs. The contents of the egg is used as food for the developing embryo. The eggs we eat are not fertilized. In other words, no baby chick is being formed in the egg.
