I am not sure if this topic has been posted before, I attempted a search but was unsuccessful, if it has, I do apologize. I have 2 7month old roos that are aggressively mating with only one of my hens. I have an older rooster (about 8 years) that I assumed would not let the younger ones mate in the first place and at the very least protect her (especially since she is the top hen) but he really doesn't do anything other than giving the younger boys a little peck on the back if she starts to scream. They have pulled out a fair amount of feathers on her back and caused some scabbing. I know the younger roos can be aggressive when mating but are only really aggressive and injuring this one. It has gotten to the point where she does not want to roost with the little flock at night and hides during the day. Today I left the younger ones in the coop/run and allowed the hens and top roo out in the yard and they were fine. I attempted to use a hen saddle but for whatever reason the older roo freaked out and started attacking her himself, which is something he has never, ever done. He is very good and gentle with his girls. Luckily, it was a little big and she was able to get it off and he stopped (could it have been because it was too big?). I do not know what to do. I thought it may just be their spurs but after checking today they do not even have them yet, still just little numbs. I know we need more hens (we only have 4 for 3 roosters) but the 2 younger roos where not meant to be but since they do not fight, (in fact they are more aggressive with her than with each other) I did not think it would be much of a problem and it wasn't for a good while. They have just started this in the last couple of weeks. At first I thought she might be sick but it is only the two younger roos that are hurting her. Would getting more hens solve the problem or is there something else going on considering they only do this to her?
