When birds lay eggs they usually sit on them and keep them warm. Just like when a human is pregnant, our baby stays warm inside our body. If we freeze to death outside, our baby would die. If the eggs aren't kept at the temperature of the parents they wont be warm enough and they baby birds will not grow inside.
Birds incubate their eggs by sitting on top of them, in essence sharing their body heat with the eggs.
All birds have to incubate their eggs, keeping them at a certain temp and turning them so the chicks won't stick to the inside of the eggs. Some birds cover their eggs to keep them warm when they are away, but most just use their own body heat
