Why do penguins have a small number of eggs in a clutch?

The Penguin is a family of birds belonging to the Penguiniformes. Penguins live in colonies on the shores of the seas, in very harsh conditions, feed on the fish they catch. Penguins, when breeding, choose a permanent pair for themselves. The female lays from one less often to three eggs, the male and the female hatch eggs in turn. Penguins are born blind and helpless, so more than half of them die from cold, hunger and predators. Such a small number of eggs in one clutch was the result of harsh living conditions. The fewer penguins a couple has, the more chances they have to survive.
