Two “gay” male penguins have hatched a chick and are now rearing it as its adoptive parents, says a German zoo.

The zoo, in Bremerhaven, northern Germany, says the adult males - Z and Vielpunkt - were given an egg which was rejected by its biological parents.

It says the couple are now happily rearing the chick, said to have reached four weeks old.

The zoo made headlines in 2005 over plans to “test” the sexual orientation of penguins with homosexual traits.

Three pairs of male penguins had been seen attempting to mate with each other and trying to hatch offspring from stones.

Stupid penguins are violating natural law.
