Hi. Heres a little back story....my oldest and largest hen, Jane is a barred rock. She has always been the queen bee and pretty much in charge. In May I got two Frizzle Cochin banty roosters as babies. They are my only roosters and obviously much smaller than Jane and most of the other hens. They are all over the smaller girls and I have seen them on occasion try with Jane and some of the other larger hens but they wont have any part of it. Well as has been normal. My birds free range during day and go into a pen with an off ground coop with nests and roosts in it at night. In this particular coop have been Jane, one other larger hen and the banty roosters. I locked them all up as usual on Sunday night and when I went out Monday morning to let them out Jane didnt look right, she was puffed up and huddled near coop door as I got closer I could see her head was all bloody. A small portion of her comb almost looked gone she had wounds behind the comb and one eye was shut and not opening. I was so upset she is my favorite girl I know she has been with the other hen for a very long time and the roosters are the newer of them all so I ASSUMED one of them must of gotten to her? She sleeps on the floor of the coop not up on the roosts and I have notcied they both sleep right next to her at night. So I left her penned up with her hen buddy and kicked out the roosters to another area. She has been penned up with the hen since MOnday and she healed up nicely and they have no issues so this afternoon I let those two out to range with rest of flock until bedtime. I observed them and the roosters did come over and try to herd them a litttle but nothing aggressive and they seemed ok just doing their own thing.....so I left them and came back out two hours later right before dark to lock them up. The smaller of the roosters was in the other coop where I have been keeping them separate at night, the larger one was not there so as I thought he was in the orginal coop with Jane and the other hen. i ran him out and put him back with the other rooster and went back to final check the girls and Jane was all beat up again! UGH! Her comb was just hanging and her head was bloody with wounds behind the comb again. I cant understand why all of a sudden this is happening? I do not think at all that it was the other hen as they were fine for a couple years before this and were fine cooped up together once she was hurt the first time. Can anyone give me some chicken behavorial info that might shed some light on this? I am only a couple years into chickens and still learning. Jane IS the oldest hen and she is molting ALOT right now much more than the other birds as far as I can tell. Any info would be greatly appreciated and thank you for reading my novel Just worried about my best girl.
