My daughter noticed this afternoon our 4 year old hen had some blood on the back of her head. I'm sure it's from our roosters. She doesn't move as fast as she used to so they are able to "catch" her easier. What should I do about it? I've read about Blue Kote not sure if anyone locally carries it or not I also read recently in Hobby Farms Chicken magazine you can use tree sealer. I thought this was my biggest concern until my daughter just a few minutes ago came and got me and showed me this What is the best way to treat this? Should I also sew up a saddle real quick to put on her as well? I think it'd cover the area this wound is at. My 13 chickens free range in my large back yard all day do you think isolating her would be necessary as well? I'd hate to do that because she is very much a flock animal. :-( She's my favorite hen that I've had the longest and I just want her better.
