I have a light brahma roo, who is currently about 9-10 lbs. He's large. I have 9 hens in his coop for him to mate with, however, the 2 light brahmas must be too young yet because he doesn't try to mate with them. He does mate with my other hens which are Dominiques, Cucko Marans, and EEs. When he tries to mate with the hens, they RUN from him. He eventually catches one, mates with them, all the while they are crying and whimpering. It is very sad to me but then I thought maybe this is normal? My girls are probably around 5-6 lbs. Is he maybe just too big for them? When he jumps on top of them and holds them on the ground I can imagine he's pretty heavy, since he's twice their size. Someone with more experience than me help me out here please! I really don't want to get rid of him because he's a nice roo, very loving to his human anyway! He doesn't crow very loud too and he's a good protector to the girls. Suggestions?
