A penguin usually lay two eggs per breeding cycle; however they lay them several days apart. These eggs usually hatch about a day and a half apart from each other.
Penguin eggs take approximately 34 days to hatch. While waiting for the eggs to hatch, the male penguin incubates the eggs, and the female penguin returns to the ocean to eat and recuperate. Once she returns, the male and female penguin take turns incubating the eggs. To incubate the eggs, the penguins create a nest out of rocks and other items before the eggs are laid. To keep the eggs warm, the penguin put the eggs on top of their feet and press them upwards into their feathers.
