List three types of egg protection?

Eggshell: The eggshell is the primary physical barrier that protects the egg from damage. The eggshell is composed of calcium carbonate, which is a hard, brittle material that is strong enough to withstand the weight of the hen and to protect the egg from mechanical damage.

Egg white: The egg white also provides some protection for the egg. The egg white is a viscous liquid that contains a variety of proteins, including albumin and lysozyme. These proteins help to inhibit bacterial growth and to protect the egg from mechanical damage.

Embryo/Chick: The embryo/chick also plays a role in egg protection. The embryo/chick's heartbeat creates a low-level vibration that helps to keep predators away from the eggs. Additionally, the embryo/chick's movements can help to strengthen the eggshell.
