I am new to raising chickens (actually I don't even have them yet........my babies should be arriving in about 2 weeks). I would like to use the deep litter method and have read a lot about using DE sprinkled on the litter. However, I'm having a hard time tracking it down locally. My local feed store has something (I haven't seen it yet, I just called and asked) that they say is DE, but the man said it is also called "oil dry". He says that it is kind of granular and that people use it for cat litter. This didn't sound to me like what you all have been talking about when you refer to food-grade DE. Any help you have would be appreciate. Are there any brand names or other names that this product might be called? I called 5 farm stores in our area and only one had any idea what I was talking about.
