HELP! My husband bought some DE at an Aquarium shop that he thought was good to use on the chickens, It didn't say it was FOOD GRADE DE, but the guy that sold it to him said he sold it to other people with 'birds' for mite/lice control. I thought it was fine, so I used it - dusted one of my birds thouroughly and then made a dust bath spot with it.... I also mixed it in their feed... they've been eating, bathing, pecking at it all day - are they all going to die now??? I'm freaking out!!! Has anyone done this - and what happened? I'm reading everywhere that it is poisonous... am I up a creek without a paddle now? I hope I haven't killed my chicas - they are just starting to lay!
