We now have two roosters out of some eggs we let a broody hen hatch in May. They don't seem particularly aggressive, although they peck at me when I reach for them, but I can pick them up and they're fairly docile. I noticed a few days ago that our oldest hen (she's three) didn't want to leave the nesting box. I was worried that she was sick, then maybe broody, but she looked OK except for a tiny bit of blood on her comb. This morning I decided to let her spend the day out of the coop by herself, and when I went to shut all of the chickens, including her, into the hen house for the night, the two boys just jumped on her. It was brutal, and she was trying to bury herself in a corner, and when I tried to get them off, she jumped on my head to get away and her comb was bloody again. Is this normal mating behavior in chickens? I've heard having a rooster is good for the flock, but I just can't watch this hen be treated this way. We have 10 other hens and I've only noticed one other being mounted and although she tried to get away, it didn't seem nearly as vicious. My husband suggested giving the hen away, but she's actually my favorite, so if anyone needs to go it's the roosters in my opinion...
