Hello! We currently have 6 chickens, 3 SLWs and 3 BOs and here in the past couple of days they have been sitting in their home because we recently got 5-7 inches of snow. We cleared most of the snow so that they could still run around but they still rarely come out, we even have tarps around their pin to block the wind as it's been pretty cold lately. I woke up this morning and noticed one of my BOs had dabs of blood on her head, I glanced around her comb and it didn't seem to have torn. I was watching all of them to see if they were weird around her or wanted to peck at her and none of them seemed to pay any attention, I threw down snacks and they all jumped in on it. Could she have injured her head on something or could they have gotten bored in the Coop and pecked at her a little? I thought when they saw blood they would start pecking at her furiously. Should I rub Vaseline on it to be safe or should she be fine? The chickens really won't let me touch them, I can get near them and maybe get one stroke in but they stand straight up and walk away, occasionally fly away which gets them all to fly. The blood appears to be dry. Any help would be greatly appreciated, Thanks a lot!
