I've read all the posts here I can find on using DE for controlling odor in the coop. Some people seem to think it works wonders and others don't. I have reservations about using it at all since it does affect honeybees and earthworms. Adding DE to the compost (where my coop sand/poop is headed) seems like a bad idea as it'll kill harmless bugs nor do I want to put it anywhere near my garden in case the bees come into contact with it. My question is whether garden/ag lime has any negative effects. If you use the pelletized form, does it harm chickens if they eat any? And does lime do a good job on odor control? I currently have six chickens and sand on the coop floor that is cleaned every day with a kitty litter scoop but that still has a distinctly bad smell. If you do use lime, how much do you use per square foot (our sand is about 3 inches thick in an 8 X 4 coop)?
