Hi everyone, Very important question...... I bought a 20 LB bag of DE from Tractor Supply, it's called Red Lake Earth Diatomaceous Earth with Calcium Bentonite. On the bag it say's, Guaranteed Analysis: Moisture, Maximum...8% Ash (Mineral Matter), maximum....95% Ingredients: Diatomaceous Earth Calcium Bentonite It also say's FOOD CHEMICAL CODEX GRADE Is this stuff safe for chickens to get rid of chicken lice and mites and safe to put in their food like it says on the bag? I don't want to harm my chickens, just to get rid of the chicken lice and the mites! Is it also safe to put on chicks? Thank you everyone who can help me out!
