Hello. I have a flock of 5 hens, mixed breeds. This afternoon i went out to the coop to bring some cold weather treats and I noticed my favorite girl had blood on her head and foot. I brought her inside for a closer look and it looks like her comb has been ripped and is bleeding and her foot has a bloody gash on it. I cleaned her up and put some veterinary balm on the injuries. She is favoring the injured foot and limping/not putting weight on it. I do have her separated from the other girls now. I am hoping that keeping the wounds clean and infection free will keep her healthy, but i'm not sure. What more can I do? Furthermore, if her sisters did this to her, how do I prevent this from happening again? Thank you.
