Hi Everyone! I have asked a million questions (so it seems) about Diatomaceous Earth. Well I ordered 10 lbs. of the stuff and WOW!! The flies are gone, the lice are gone, and the worms seem to be going away since my birds sound 75% BETTER!! YAY!!! Anywho - I just bought a 50 pound bag through ebay. I want to work this into their everyday diet. I feed my ducks, geese, chickens, & sometimes the goats all together. I tried separating them, but they just think for some reason that the other animsl food is better so i mix it all up. One scoop of goat, One scoop of layer, Once Scoop of duck pellets, & One Scoop of Crack Corn. I mixed the DE in the layer, since it is finer and it mixed better.. Just a few TBSPs in the scoop. Now my question is.. How much DE per 50 pound bag of feed? Should I mix it into all the feeds? I want to make sure all the animals get enough. I read before a large coffee can filled per 50 pound bag. Is that accurate? Should I put a coffee can filled in each 50 pound bag of feed? Including the crack corn? Can I feed a little to my rabbits? Can i mix a coffee can filled in thier 50 pd bag. Does that also apply to dogs and cats? I just want to make sure I am doing it right so i dont waste any of it! One more thing - Read in one of my previous questions about taking a flower sifter and sifting the DE around to elminate flies.. How much should I sift around the barn yard? I only put some around where the goats eat (cause the flies were bad there) and under the chicken coop and the flies are gone! YAY.. but there are some other areas i would like to do and if using the flower sifter works.. i just want to make sure I use enough and not too much. Thanks again for all ur help!
