Penguins don't really sit on their eggs. They put the egg on their feet and hunch over a Little so that fold of belly skin drapes over the egg to keep it warm. And both males and females take turn, so that the other can eat.
Yes it does so the egg is warm and so the female can go get food.
Incubation
After the penguin egg is laid, the male will sit on the egg while the females leave to find food. The males will sit on the eggs for a full two months before the egg hatches.
The male penguin sits on the egg while the female penguin goes out to see for fish (food). His bod fat helps keep the egg warm and protected from the harsh elements. Once th chick is hatch, the mother returns and shares the food she has caught with the chick.

They raise their young by putting the egg under the flaps of their skin in between their legs. The male penguin uaually take care of the egg until it is hatched. When a mothers egg is lost or stolen the male penguin steals another penguins egg from their nest. They do this so they don't really feel bad for losing their young.
