I have 12 hens, born this past March (a few just starting to lay now). A friend had an unexpected roo in town and needed to get rid of it. I told her I would take it and try it out. The roo is a EE and about the same age as my girls. So I had them separated for about 1.5 weeks and then put them together. They attacked the roo. He fought back a tiny bit in the beginning and ruffled his feathers and then they just beat him down. Now he doesn't fight back at all. Just cowers down or runs until he gets away and goes to the coop. He will stay in the coop all day to stay away from the hens. They pretty much leave him alone in the coop. The last few nights I have been putting him up on the roost poll to sleep with them. Else he sleeps in the nest boxes if I don't. It has been almost a month. Will they ever get along? Will his hormones rare up and he will start taking his place in the flock? It is so sad to see. He has bald spots from them ripping feathers out and his comb bleeds sometimes from those nasty girls. Also, when he first arrived he crowed a couple times, and now no crowing.
