I just got 22 chicks from Ideal on Thurs. A few of them seem to have pasty butt, and I have cleaned them with warm water and paper towels. I read some earlier posts on this, and someone said that the chicks need to have some kind of probiotic mixed with their feed until about 4 months old. All I have on hand right now is a canister of Revitilyte Plus, which is an oral electrolyte with vitamins. It does have acidopholus in it, so wouold this be o.k. to give them?
