My hens won't lay in the nesting boxes, and always manage to lay in a dirty (poopy) section of the coop. I've tried every tip I've found here and elsewhere online -- eggs or golf balls in the box, moving the boxes, changing boxes, giving them privacy, etc., etc. -- and they always seem to pick a spot in the coop right under one of the perches. It doesn't matter which perch, as long as there's a perch. They also lay out in the wooded area of our fenced yard; these are the only clean eggs I ever get. I try to keep them in the enclosed coop/run long enough for them to lay, but some of them are quite determined. (One of our girls disappeared last spring and returned with nine chicks, five of them roosters!) I don't want to search for eggs every day, and I don't want to keep finding eggs in excrement. Yuck. Help!
