I want to control flies, bugs, pests in the coop and run for the chickens and control odor (we keep a deep littler method with pine shavings and so far not too smelly, it gets turned everyother day and kept dry.) We are just starting out first timers, some of the chicks are almost 2 months old and the jap bantams are younger, about 1 month old. i have been told by TSC that Sweet PDZ works great for moisture, odor and bugs and is safer than DE food grade. Has anyone had any experience with these to compare? Thanks.
