I have 6 Leghorns (approx. 7.5 months old). They have a very comfy coop and large run in which they spend most of their time. A couple times a week I let them out to run in the yard. This evening when I went to close up the coop for the evening I saw one of the hens cowering in the corner of the coop while another hen was pecking at it furiously (we don't have any roosters). The hen's head was a mess: covered in blood, the back of the comb is split, etc. I tried to take a pic (see below) but it didn't turn out very well. I don't know if the hen got injured and then the pecking started or if this was all due to pecking. I brought her in and have her in a bin in our basement - not ideal, I guess, but I don't have anything else at the moment. I figured it would be ok for the night. What do I do now? Should I wash it off? If so, how? I read in another post that applying neosporin is a good idea. Is that right? I've read that I need to keep them separated until the injured hen heals but does anyone have any idea how long that usually takes? I do not have another coop to keep her in. I could borrow a large dog crate or something of the sort tomorrow - would that work? Any help, ideas, suggestions, etc. would be greatly appreciated. Thanks so much!
