They've been in the coop now with my 2 older ladies for about 4 weeks and I don't have a clue how to stop them from doing this. The boxes are getting nasty and they've got a perfectly good roosting pole. I even put their little one in there (that they had in their brooder, for familiarity) when I first moved them in. Thought that would help prevent this. Any thoughts on how I can discourage it, but still leave the boxes available to the 2 laying hens? Definitely don't want to discourage them!
