My BO is broody...sitting on golf balls! when i take her off the nest and let them free range, i lock them out (hoping to break her). I've removed all golf balls and eggs. she walks around all puffed up and if she comes within 20 ft. of another hen, they pounce her...she screams and runs. she keeps trying to join the flock, but the minute she puffs up they attack. do i just have to wait it out?
