(AP) — Omaha’s Henry Doorly Zoo has unveiled its newest additions.

The zoo announced Tuesday it has five new rockhopper penguin chicks that hatched at the zoo between Dec. 23 and Dec. 27.

Zoo officials say adult birds typically raise their own chicks, but increased activity in the exhibit led to the decision to hand-raise the chicks, which weigh about a pound each.

They are being fed a fish and krill formula five times daily. The chicks are also allowed to eat small fish filets as they work their way up to whole fish.

Zoo guests will be able to watch the chicks via video at the penguin exhibit until their waterproof feathers come in.
