Though most birds incubate their eggs in a nest, King Penguins have taken a different approach to keeping their eggs warm and off the frozen ground. After the female has laid a single egg, both parents take turns holding the egg on their feet, under a specially formed bulge of skin. The shifts last anywhere from 6-18 days, giving the other parent time to forage. A chick will continue to balance on its parents’ feet up to a month after hatching.
