I went into BigR today to ask if they had Diatomatious Earth. I have read in a couple of books and post on this site that you mix wood ash, sand and or diatomatious earth for the chickens dust bath. My chickens are a few weeks old but already they are bathing themselves in the wood shavings. I wasn't going to get the bath together for them right now but I am working on their coop. In any case when I asked the sales man at BigR about the diatomatious earth and what I am going to use it for it looked at me like I had lobsters coming out of my ears...'I have never heard of that before!' in a stern voice was his reply. Wondering if perhaps I was wrong about what I read or is he not up on his chicken care?
