Sometimes the penguins wait their turn but other times they hop right over the scale or jump on two at a time.

This video from November released by the zoo on January 5 shows a keeper using a tiny fish called a capelin as a treat for positive reinforcement.

The penguins at the Milwaukee County Zoo are weighed once a month and keepers keep track of all the penguins by the band on their flippers.

The Milwaukee County Zoo has 16 Gentoo and Rockhopper penguins.
