Just found my buff Orppington under the chicken house laying on 17 eggs! It is dark and the other hens are roosting in the house , but she refuses to come out from under. I removed all of the eggs she was laying on and offered her some cracked corn to lure her into the house, but she will not budge. What should I do? I'm afraid to leave her out, but I'm also afraid to leave the chicken house open.
