It’s A Rockin Hopper Boy

The Penguin Post has learned that the gender of the Shedd Aquarium’s newest addition, a baby rockhopper penguin that hatched in June, has been determined and it’s a…boy.Rockhopper-Penguin-Chick_2-300x200

Animal care staff at the Shedd confirmed that Chick No. 23, as he is still known, is a male through a genetic test conducted during a recent check-up, according to a statement from the aqaurium, since there are no observable sex differences in rockhopper penguins.

The chick hatched June 9, and has already nearly reached his full adult height of about 18 inches, according to the aquarium staff. He currently weighs about 4.5 pounds, up from 2 ounces when he hatched.

The penguin chick has been exploring his habitat on his own, learning to swim by himself, and accepting food from trainers after being fully weaned from his parents, and now that his gender has been determined he should be named soon (as chick #23 is not really a cool name).

Rockhopper penguins are considered a vulnerable species. The Shedd is currently home to more than 30 and has been part of a breeding program since 1991.
