OK, got some DE. How much do I put down for the birds to dustbathe in? Do I mix it with sand? I bought a lot because I need it for several pests. And I'll be posting further questions in other locations, to stick with the appropriate animals. If I put it in a sandbox type thing will they go in there to dust bathe? Or should I just look for a place where they take dustbaths and put (how much?) DE? How do you feed it to them for worms? Will they just eat it or do I mix it in with their food and again, how much do they need? Any help on how best to use DE for maximum effectiveness would be greatly appreciated. I have lots of ants, there are fleas, and I think the chickens have mites as they are scratching.
