Hi Just wondering what the best dust bath mixture is. I feel like I tried everything. My girls are clean (no buggies.. Thank the Lord) I'm just trying to avoid any potential mites/lice issues. Currently I have a little Tykes Kids Playhouse filled with peat moss, DE, sand and ash. It doesn't seem like they use it. It looks like the DB under their coop. So I've been tossing some ash and DE under there as well. I'm wondering why they don't use anything I've made for them? Any suggestions?
