I got some Sweet PDZ today and am working on cleaning up my coop, so I can apply it. I plan on just having PDZ in the pull-out roost/poop pan, and shavings in the nesting boxes (with a little PDZ underneath). Down in the runs, I'll most likely use deep shavings again, with some PDZ under them. I have been putting food & water in the roost, and sometimes down in the run too. Should I be doing this, or only put food/water down in the run? I don't have a problem making them walk to get it. It seems like it'd make an unnecessary mess in the roost to keep the food/water there. In the pic, the nesting boxes are to the left, the roost is behind the little window, and the run is below the window and roost pan.
