Every year, female and male penguins get together to mate.
Penguin mothers lay one or two eggs in a nest. The nest can be made of grass, a circle of stones, or a burrow under the ground or ice. The penguin mother and father take turns incubating the eggs, which takes between one and two months, depending on the species. The chick then chips it way out of the egg.
When the chick grows up, it finds a mate, which it usually keeps for life.
