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.
"Then we made the decision not to give it up and instead try to give it two fathers."
So far, the experiment has been a success. The two foster dads incubated the egg for 30 days until it hatched and have continued to care for the newborn chick.
