Hi, I had the same problem. I aksed here on the board and quite a few people helped me. I finally got a chance to look at the websites suggested and then armed with the specific names of companies and more specific info I went to my local feed store (where I got my chickens from) and asked if they ever got anything from PERMA GUARD.....they said yes and I told them that PERMA GUARD sells food grade DE. They have ordered it for me. Where did you get ypur chicks from? I would go there and ask them if they get products from PERMA GUARD, if so then they should be able to get DE. But if you do happen to find it anywhere else, make sure it is FOOD GRADE DE. Dont let anyone tell you it is and they just dont market it as food grade, they are lying. mary-kay
