I have 4 blue Swedish ducks (3 drakes and 1 hen) and 2 young chickens( both pullets, 1 barred rock and 1 buff Orpington). My ducks are about three months old and they haven't fought each other yet. I was wondering if when the Ducks and chickens get older will my 3 drakes fight over the one female duck then try to breed with my chickens? If there's going to be a bunch of fighting going on would it be best to get rid of 2 out of the 3 drakes? Or would I be better off getting rid of all the drakes?
