I have a hen that has been sitting in one of the nesting boxes for a couple of days now. She has rolled all the golf balls under her, I have removed them. I take her out at least once a day to get some food, water and stretch her legs. The other hens all peck at her and are being mean. Should I break her from being broody? If so , how? Or how long does this last? Also , I have another hen that is jumping on top of the other hens backs and riding them, acting like a rooster. (I do not have a rooster) if you know what I mean. Is this normal?
