I have a lot of floor space in my coop, or I should say my "hen's" coop. Anyway, its filled with about 8" of shavings. Their run is 2/3 sand, 1/3 soil and they have a ton of fun scratching around taking dirt/sand baths. Before I got them they only had rocks and no place to scratch around in. So, today I set up a a shallow tub in the coop and put in some of the sand/dirt mixture with some DE. That way if it rains or the ground freezes in the run they can still roll around in the tub. The tub isn't too shallow and I do expect some of the contents will fly out, but I can't see any problem with that. Does anyone else have an in-coop tub? Any problems with it?
