I have 8 hens. 7 of them lay in the nesting boxes. I have 1 that refuses to and is laying in the corner of the coop under the roost (talk about not the cleanest place) How can I stop this one from doing that and is there a reason why? I have 8 hens and two nesting boxes. Both about the same size although they like the one more then the other. Both are soft and have pine shavings in them.
