I have 1 roo and 2 hens. Neither of my hens are laying and my roo seems to have made friends with 1 hen who he doesn't mate with. My 2nd hen is getting terrorized by my roo since he's turned all his attention on her. Why is he only mating with 1 of my hens and do I need to get a 3rd hen to solve this issue? When the hen he is mating with comes out of her coop (which is rare) he becomes aggressive towards her. Any advice or suggestions are appreciated!
