I've read quite a few comments about coop bedding and I see there are many opinions but my question is, How do you clean it if you use anything besides sand? I have a poop sifter I use every day but how can you use that if you have straw or wood chips? Do you just let it pile up and eventually break down? I actually have bare dirt in the coop which is rather loose so I can sift it. The run on the other hand is large and totally natural. Like a compost bed. grass clippings, leaves, garden waste. It stays pretty nice but I don't think I want the poop to build up in the more enclosed coop do I?
