My nesting boxes are higher then the roost so my chickens sleep on top of the boxes, so of course they poop in the nesting boxes. I have blocked so they can get on top they still manage to get up there. So my dumb question is. is there any reason why I couldn't put a piece of wood on top and extend the top so they can still sleep up there but then they will just be pooping in front of the boxes instead. Other suggestions?
