penguins

Happy Father's Day to a gay penguin couple in Germany's Bremerhaven Zoo.

The couple has been fostering a chick given to them by zoo handlers, after the egg was rejected several times by its biological parents.

The new dads are one of three same-sex couples in a colony of twenty at the zoo. Scientists originally tried to split-up the couple to encourage breeding, but the they continued to come back to each other.

Since hatching a few days ago, the chick is thriving!
