"The new family will be off exhibit for a few more weeks, until the young bird's adult feathers have grown in," said Martin Vince, curator of birds at Riverbanks Zoo and Garden.
Young penguins have a tendency to wander from their parents and can easily fall into the water before they get their adult feathers.
The feathers are important because they provide waterproofing and insulation from the cold water (40 degrees Fahrenheit, to be exact).
"Zoos often hand feed baby penguins to ensure their safety.
For this gentoo penguin, we found a happy medium that kept him with his
parents, but eliminated the significant dangers of prematurely falling into the water," said Vince
