After doing research and reading so many posts on this site about DE I was under the impression it helped with fly control. I bought a bag last Friday and sprinkled some over the coop flooring, in the nesting boxes (although the chickens don't use them yet), I put some over the roosts and mixed a bit with the food. There has been no improvement 
I know the directions on the bag say it is to help with crawling pests. So is the only reason people use it as fly control because the chickens can eat it and then it's in their poop? I'm bummed I wasted the money on it.
