As per the link, a penguin couple at a Zoo did not want their egg and kept kicking it out of their nest, so the zoo keepers decided to rescue it and gave it to one of three gay male penguin couples at the Zoo! It goes on to say that homosexuality is well documented in the animal kingdom.
I just think this is a great story and is more proof that it is perfectly natural for both people and animals to be hard wired for homosexuality. I wonder if those who think homosexuality is wrong and perverse will start a group to have the egg removed from the gay penguins, because you wouldn't want that little egg to turn out to be gay too!
