I'm new at this...this is my first post...Hi! Anyway, after reading about sand, it sounded perfect. dust baths, smooth chicken feet, and unlike deep litter, they can dig through to get worms. But I'm not able to simply rake out the poop, as was asserted in the various articles and forums. The girls walk on it and it gets mixed in with the sand and I'm wondering if it will end up being a health hazard for them.
