Hi! So my flock had a bad case of IB last fall. Many survived, but symptoms reoccur with stress. I've been using deep litter in the coop. I turn the pine shavings every day and add in some to the top a few times a week. I've been reading about sand lately and was wondering if that might be better for them in the coop. I want to keep the dust to a minimum. Does anyone know if sand or pine shavings are more dusty? thanks!
