I got home today and found one of my Buff Orpingtons with a triangle cut in her head/neck kinda folded torn skin. I noticed it cuz her head black on one side (dried blood.) It wasn't bleeding so I examined wound and was able to lift flap and it was clean no bleeding so I applied tripple antibiotic ointment on the wound. I also applied vicks to her good side and a few inches down her neck to hopefully stop other hens from pecking her. I crawled everywhere on my knees (hens looking at me like a fool) looking for anything that could have done this. I found a couple spots on the pop door openeing where i used hardware cloth to join coop to run and i actually cut my finger running my hand around opening. Could this have done it or do you think one of the other hens could have done it. The one that got wounded is my girl she is the one who comes to me the most and actually if I let them all out she will come down to the camper and join me sitting at the table playing cards. I combed the coop and run and there is no signs of entery. My coop and run are on my byc page. Thanks, Dave The hens don't seem to bother her nor are any of them skiddish. She was fine at 5:30 am when I went to work.
