CHICAGO — It’s a boy! The Shedd Aquarium’s three-month-old rockhopper penguin chick has been confirmed as male.

Even though the chick was born June 9, his gender was only recently determined by a genetic test conducted during a recent check-up.

While the chick doesn’t have a name, he is currently known as Chick #23 — he’s the 23rd rockhopper penguin to be born at the Shedd. He currently weighs about 4.5 pounds and has nearly reached full adult height of about one-and-a-half feet.

he gender announcement comes as animal care staff prepares for molting season for its Magellanic and rockhopper penguins. During this annual occurrence, the penguins will shed their waterproof feathers over the course of two to three weeks to make room for a brand new coat.
