The Topic:

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. Inside of an egg shell is a yolk, embryo, albumen (white), and membranes. 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. What remains are nutrients such as proteins, carbohydrates, fats, vitamins, and minerals. People have collected and eaten eggs for thousands of years. Most of the eggs people eat now come from domesticated birds such as chickens. Eggs come in different sizes, colors, and grades. People in countries all over the world eat eggs.
