I have a BR who has always been kind of odd and has a tendency to bite people, and in the past few months she has begun pulling the neck, back, and vent feathers out of all the other hens her age. I have given her catfood (which she wouldn't eat), she and the others free-range 1-3 hours per day, the coop is not too small, and I provide weeds and kitchen scraps for them to prevent boredom. Is there anything I haven't thought of? If I completely isolated her for a time, and then reintroduced her, would she be lower on the pecking order, and less likely to pick at their feathers? The egg she lays everyday is certainly valuable to me, but I hate seeing half the flock practically bald and hearing their squawks whenever she does it. Should I get rid of her?
