I do have DE food grade, but do not use it as feed supplement. I only use it as bottom layer on coop floor. (scrape thin layer) and cover that with about 1/2 inch, (about 1 cm) of Sweet PDZ. That is a stall freshener, for horses, but works very well in chicken coops. and cover that with a layer of hay. I used same method in my pigeon lofts.
The DE is there to control insects and mites that may be crawling on coop floor.
I also use the DE with caution, and wear a respirator mask when applying. If you would view it under a microscope, it resembles crushed glass. It controls the insects by cutting action on their body shells. (
exoskeleton ) Best to avoid inhaling DE.
