Hey pdirt, I like that you upgraded your formula in post #8. I've been feeding fermented feed w/ACV but I've been waiting for the AEM to be ready to start transitioning over. I have my chicks (6 wks old) out in the coop and with the deep litter I'm going to start spraying down the area. They have been on FF since day 1 so I've never had any trouble with the poop or smell. It just disintegrates.into the litter. I'll let you know how it works. Thanks for all your help. Linda
