• Since it’s so cold in Antarctica, if a penguin were to lay her egg in a nest like other birds, it would freeze.
• To keep the egg warm, the mother penguin gives the egg to the father penguin and he holds in what is called a “brood patch”.
• A “brood patch” is a warm fold made of feathers and fat that rests above his feet.
