Bird eggs have a hard outer shell composed of calcium carbonate that protects the developing embryo. Inside the shell, there are membranes and albumen (egg white) that provide nutrients and support for the embryo. After the eggs are laid, the female bird will typically incubate them by sitting on the nest to keep them warm until they hatch.
