I have a pen made from pallets. It's somewhat close to the ground but the bottom side has hardware cloth on the outside that wraps up the sides under the siding. A week ago I noticed a spot of blood on the perch and found one of my hens has had a toenail bitten? off into the quick. A little cornstarch and all was well. A week later the SAME hen has now had the same toe on the other foot bitten? off but this time into the end of the toe. It took a little pressure along with the cornstarch this time to stop the bleeding. So I'm trying to figure out what's happening here. Now here's the situation. We have 3 RI hens. One of them (Blondie) is the bossy queen of the roost and the one getting her toes bitten. Two weeks ago we acquired a young rooster. Belvedere is only about 5 months old and my first thought is that he is doing it but I can't see it. He is a big scaredy cat. The hens have him hen pecked and Blondie especially will chase him back in the coop when he comes out. He has in the last few days been brave enough to come out and stay out. Blondie will drop kick him with both feet sometimes and he literally runs into the coop. I installed a second perch on the other side of the coop because they wouldn't let him perch. I put him on it the first two nights and then one of the three hens (Joan) who is always picked on started perching there. I guess she figured she gets away from the other girls picking on her. Belvedere would roost on the floor, sometimes under the perch that Blondie is on, sometimes under the other one. I try to put him on the perch with Joan and they seem to be okay together. Some nights he gets up there with her on his own. The other night I left him be, he was perched on the floor under Blondie. He is such a gentle fellow who doesn't seem to have a mean bone in his body so I find it hard to believe he could be doing it. Then I saw posts about mice and rats. I suppose they could be getting in? but would they be getting up on the perch? Why wouldn't they be attacking Belvedere who is sometimes on the floor roosting? He'd be an easier target, no? Or why not just eat the feed? Why the same hen both times and on the same end of the same perch? Both times it was her back toe and she seems to be walking okay. In fact, everyone is still laying eggs and doesn't seem terribly upset. I think I'm the only one upset by it all! LOL!
