This afternoon I saw my rooster, a 26 1/2 week old large-sized (I don't know his breed-- possibly half leghorn/half Buff Orpington or EE) mate with my tiny Sebright bantam! I was horrified. I didn't think he was mating with her, because of the size difference. I am so worried he could hurt her. He tried mating with her twice within a 10 minute period, and she squealed. I think he has just started mating with her-- I've never seen this before. However, a few days ago she slept all night under the nesting box, which I thought was weird. She came out the next morning. I wonder whether he might have mated with her for the first time that day, and it shocked her. He has a 2 year old Barred Rock to mate with, as well as two half white leghorn pullets who are his own age. I was told that 3 hens are about right for one rooster, but I've also read that 8 - 10 hens is the best ratio for one rooster. But I also read that a rooster will mate with all the hens he has access to, so I'm not sure that getting more hens would solve my problem? What do you think? He might mate less with the Bantam if he had more hens, though? I've read that a large rooster can dislocate a tiny bantam's neck or cause other injuries, rare though it might be. What do you think I should do? Should I try to keep the little Bantam away from him?
