Cathey, are they pecking each other? Do you have one or more roosters with them? That would be my first guess, that other chickens are doing it. Best choice then would be to either give them more room by letting them out or building a bigger pen, or to reduce the number of hens you have (and eliminate roosters).(posted 9678 days ago)Otherwise, make sure they're getting a good diet, plenty of calcium and grit.
