I also put this in the coop/run design forum just in case. I'm starting to use PDZ today, and am making a few changes. Instead of shavings in the pull-out roost pan, I'm going to only use PDZ. The nesting boxes will stay with shavings, maybe some PDZ under them. The run will most likely still be deep shavings, with some PDZ under them. Until now, I've put food/water in the roost, and sometimes down in the run too. It seems like it may be a big mess to continue doing that. Should I only be putting food/water down in the run? The roost is behind the little window, and the run is below that.
