"Germany’s Bremerhaven zoo reports that two “gay” adult male penguins have hatched a chick and are now acting as its adoptive parents.

The male penguins, Z and Vielpunkt, were given an egg that had been rejected by its biological parents, the zoo said on Wednesday.

Z and Vielpunkt reported to be happily rearing the chick, which is now four weeks old.

Bremerhaven zoo made headlines in 2005 when it announced plans to "test" the sexual orientation of penguins with homosexual qualities.

Three pairs of male penguins had been observed attempting to mate with one another and attempting to hatch offspring from stones. So the zoo brought in four females to try to get the penguins to reproduce, but abandoned the plan shortly thereafter amid outrage by gay rights activists who accused the zoo of meddling in the animals' behavior. The six "gay" penguins, which include Z and Vielpunkt, remain at the zoo."
