I have a small flock of 6. 2 buff orpingtons, 2 australorps, 2 wyandottes. 4 of the 6 have been brutally pecked and are actively bleeding. I took the 2 girls that were uninjured and separated them. Any suggestions on what to use to isolate the other 4 so they don't peck each other to death? All of them are pecked in the same place... large spot right next to the vent. When I went out this morning, one of them has also had all of her neck feathers removed. I don't know if they have already suffered too much damage... how much damage can they take and still heal? Also, I don't know which one of the uninjured are doing the initial damage, or if it's both of them.
