Looking better today, not scabbed yet. Skin intact no feathers and red. My brother n law ( a long time chicken keeper) came over and agreed I had to separate or they would make a bigger wound and if they broke skin and caused bleeding she would get attacked. She is a look can’t touch area. I just integrated 3 new pullets- same age as flock) a week after seeing her peck wound) so pecking order is all in an upheaval. No fighting! Thank goodness, just some out of my way, little chasing but no pecking. The lower rank RIR are doing the chasing. Also the one last pecking the injured. I think they are trying to improve their ranking ( from what I read on this site) All others are pretty much ignoring new comers.
