Keepers at Germany's Bremerhaven zoo couldn't get two penguin parents to take care of their egg, so they're trying an experiment — they gave the egg to a gay male penguin couple.
The biological parents "always rolled the egg out of their nest, they kicked it out again and again," zoo veterinarian Joachim Schoene said.
