Shedd’s newly hatched Magellanic penguin chicks are small enough to fit into your cupped hands—for now, anyway. These chicks range from 15 to 24 days old. Fast-growing, they tripled in size during their first week. Once they’re fully grown—by late summer—they’ll settle into the renovated penguin habitat in the Oceanarium’s new Polar Play Zone exhibit. Adult Magellanic penguins are around 27 inches high and weigh 7 to 9 pounds. Learn more about penguins.
