I am considering trying out the deep litter method after reading about it on this site. I am curious about the food grade DE- as it is supposed to help control some pests, etc. I didn't know if there is something in it that I should be concerned about? I see obviously that it is food grade (but look at what we put in our bodies sometimes! ) but I can't help but wonder if it contains harsh components or something. Ideally I would like to keep things organic as much as possible. Thanks for the help! I am also open to any other suggestions- just trying to figure out what is the best way to keep down smell and flies and keep things reasonably clean.
