We have a mature peacock and hen we purchased as a pair and a young peacock that is getting some train feathers now. All three free range (until I get a pen built, tired of poop on all my patio furniture). The hen obviously prefers the youngster and spends most of her time with him. I am thinking of selling the younger as we don't need two males. Or at the very least pen the two and leave the young male out. Will she mate with the male that she doesn't seem to prefer?
