I just acquired three new hens, a black sex link, an olive egger and an easter egger. These three had been raised together and I thought that introducing them to my existing flock would go okay. Wrong! My ladies beat up my new easter egger! She is terrified and I had to remove her! They picked the top of her head clean of feathers! What should I do? I don't want to get rid of her she is so sweet! Any ideas?
