I have 10 hens. I was getting 8-10 eggs a day and have had a few hens try sitting and simply removed them from the nest a few times and that stopped it. But right now I have one who has been sitting for nearly 3 weeks and removing her has no effect. She is losing her feathers on her breast and I'm worried she isn't eating. The nest is empty but she continues to sit. Also , aince she has been sitting my other hens have not been laying well. I now only get 1-4 eggs a day. Any ideas on what is going on with my other hens and how to get the sitting hen to STOP sitting?? Also, we have 3 nests and they will now only lay in one. Previously they used all 3.
