A pair of gay male penguins are raising a chick in Germany's Bremerhaven zoo. The little chick was abandoned by its parents while it was still an egg, so the penguins put the egg in their nest and incubated it for 30 days. Since the chick hatched, they have continued to care for it.
If you're wondering how the zoo knows the penguins are gay, the pair has tried to mate with each other before, and they've shown no interest in female penguins. The zoo says: "Sex and coupling in our world don't always have something to do with reproduction."
Of course it's unclear if this would be allowed at the Arkansas zoo, since voters in that state outlawed gay adoption last November. If you're curious, here's a rundown of where gay adoption is legal in the US.
