We have a mixed flock, 2 Plymouth rocks, 3 ameracaunas, 1 favourelle and 2 other chickens we were given. Typically the chickens do great add the original group were raised together. We had one chicken that was ostracized by the flock. We had another favorelle that we lost a few months ago to a possum attack that was ostracized after she had to be delegated due to a leg injury. When she returned she was picked in and then ignored entirely. everyone had been getting along until today. I called the girls to give them a treat and noticed one of the ameracaunas had an injury in her head and was missing an eye. She was fined last night when she was in her coop with everyone else. Now the other ameracaunas are attacking her. We removed her and cleaned her wounds. She is in our garage right now because I was afraid they would hurt her. What should we do? She is so sweet!
