We use FG DE in our coop for years but never a brooder. In the coop, I use an old parmesan cheese dispenser and yes, just sprinkle around the coop only, not the chickens, about once a month keeps the mites/lice away.
We use horse bedding pellets in both coop and brooders. Keeps both dry and odor free. And grit in case they eat any of the sawdust it makes by the water bottle.
