If the article is true, then people could buy non mating pairs, and still be able to have a boy and a girl and not have to worry about breeding!! great
But I think that if you split the mating pairs up, they would be awfully depressed, wouldn't they? I've seen a swan looking for her mate, as they are one of few monogomous species in the world, and I swear, her face was so full of sorrow, it broke my heart.
Also its cute that the males play with the young, Also I agree I wouldnt want to split up a mating pair just so I can have a non mating pair I'd rather have the male neutered or just let them be happy and breed but then i'd have to many so yeah neuturing would be the way to go.
