Maybe she is is just an easier target. Maybe the other hens dont allow him to mate them as much, so hes "deprived". Usually hens prefer older more mature roos, especially if they are older themselves... oh, i just went back and read where you said the other hens refuse to let him mount them, so what i said about her being an easy target is likely the case. Theres to much competition among the other roos, so he likely just takes what he can get and takes advantage of her since he knows he can. I have found 1 roo to 14 hens is a good ratio for me, so 3 roos to 10 hens is probably way to much over breeding for the hens and under breeding for the lower roo. Not a pleasant combination. He can seriously hurt her and i would recommend finding him a new home. He seems to be the problem roo to her. Not that its his fault, but he would probably be better off in a flock of less roos and more hens. Or, start him a flock of his own. However, being free range, that would be quite difficult.. If he is pulling feathers and terrorizing her, yes, he is being to aggressive and hurting her, even if it may not seem like it to you. Over breeding or mounting multiple times can cause vent damage and reproductive damage as well, so his "hurting her" may be more than what meets the eye.
