My 50 lbs. of DE came yesterday. The end of the box was chewed up pretty good. Some DE had spilled out and the box end was retaped with about a pound of packing tape. I wonder if it triggered a biohazard response at UPS when the bum tossed the box hard against the floor . Anyhoo, the chooks are in heaven. I mixed a couple quarts into their dust crater, and they're going to town. Dorothy is hogging it though while the others stand around wishing she'd get out and let others have a chance.
