Hey Y'all, Woke up this morning and fed the meat birds right at dawn. I come back 2 hours later and I noticed that one had a bloody neck. My fiance and I took her inside and washed her neck off in the tub. It revealed this small little gash about the size of a BB. There is only one tiny little spot where an animal could possibly reach its hand inside the coop, but I seriously doubt that happened. I was thinking that maybe during the feeding frenzy she got stepped on and a nail of another chicken cut her. We cleaned the wound with betadine and put some corn starch on the cut to stop the blood. What do y'all think caused this?
