Sometimes the first egg is hatched, but if so, produces a smaller, weaker chick. unremarkably penguins only raise wholeness chick: that from the second egg. both(prenominal) the males and the females take turns incubating the egg, and feeding the chick after it hatches. The other one goes out to sea to feed itself and bring back forage for the chick. The chick is born scrawny and naked, but soon acquires a coat of thick down.
