I have 2 black chickens that always eat my red turken rooster feathers and wont stop leaving him alone.... He used to look very pretty but now those 2 chickens ate all the feathers in his butt area and half of the feathers on his back and he looks very ugly now (he is the dominant rooster and is older then both the hens) ... There is no blood from them eating his feathers and he's not injured at all, but I want to put a stop to this feather eating. For some reason they only eat his feathers and don't bother the other chickens.. What can I do? I always put feed for chickens and there always have a full stomach, but for some reason those 2 hens still love eating his feathers... HELP!!
