I have a very stubborn broody buff Orpington hen. I keep moving her off the nest and taking away the eggs, but she goes right back in. I want her to get up and eat because she was a lean bird to begin with and I am afraid she will get too thin. She's pulled out all her feathers on her belly too. I've tried closing up the coop but she lays down by the side of it and won't move. I was just wondering how long these broody periods normally last because I think it just has to run its course. Any other suggestions of what to do?
