There’s a second baby Humboldt Penguin at the Woodland Park Zoo. The newest chick was born on Easter Sunday and is a sibling to the chick born last week. The two are offspring of three-year-old parents Dora and PJ.

The older chick, hatched a week ago, doubled its weight in just six days. The above video, produced by Ryan Hawk of the Woodland Park Zoo, shows the older chick getting checked out by penguin keepers John and Celine.
