From Wikipedia:
*(pronounced /ˌdaɪətəˈmeɪʃəs ˈɝè/) also known as DE, TSS, diatomite, diahydro, kieselguhr, kieselgur or celite is a naturally occurring, soft, chalk-like sedimentary rock that is easily crumbled into a fine white to off-white powder. This powder has an abrasive feel, similar to pumice powder, and is very light, due to its high porosity.
Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae.*
It is used with poultry as a natural defense against external parasites and a wormer. It also helps keep the smell down and repels flies. It helps dry up the droppings as well.
You can find it at farmer's co-ops, some online stores and there is a BYC member that sells it (Spatcher).
THE ONLY TYPE OF DE THAT IS SAFE TO USE AROUND POULTRY IS THE FOOD GRADE TYPE.
