I've used DE and Stall Dry in the chicken coop and duck houses but am not happy w/results in the duck house. Winter is upon us and I am not going to be changing out ALL the pine shavings every two weeks. The barn lime says it's non-caustic and is safe around all animals PLUS it's only $1.99 for 50lbs. It actually seems less dusty than DE. I bought some and raked it into the gravel in our carport after having 50+ Scovies spending a lot of time in there thru the summer. The carport gravel was pretty awful. It seems to have helped a lot in the carport and the Scovies still go in their and don't seem to be troubled by it. I thought I could rake up the shavings and throw in some barn lime then cover it up. Anyone use the stuff & what do you like or not like about it? Sorry about the edit.... can't spell tonight.
