One of my BO's has gone broody. She sits in one particular box best I can tell, all day. In trying to get her out I literally tipped her over because she refused to move. Kind of funny to watch. Does this mean she is not laying? If not I'm not sure how to isolate her from the nest boxes without preventing the other three from getting to a box. My dh and I both work and aren't around to kick her out during the day. Any suggestions?
