I had an old English bantam hatch 5 baby chicks about 3 weeks ago. Today I kept hearing painful peeps. I went and checked on them throughout the day. She is plucking their feathers and eating them. One is now bleeding because she won’t stop and they’re staying away from her. I since took her out. Should I keep them separated? Should I put her back with the rest of the flock? Should I give her extra protein and put her back in?
