Well, we just barely touched on what I was looking for in that thread.... I have shavings in my coop but the girls have scratched out some straw from the nest boxes.... it seems to mix well and stay fluffy that way, and since my coop is waterproof, it has stayed pretty clean for over a month now - I just pick out an occasional poop (maybe 3 a week) since I put in a roost with a removable tray beneath it to catch the poop. What I was looking for was some advice on putting straw out in the run..... they need something to scratch through, but it seems like it disappears pretty fast, so I know they must be shredding it and eating it when it gets small enough. Is this going to hurt them? I have grit out for them all the time, and they get greens daily in addition to their layer pellets.
