I'm in a rush to start a chicken on probiotics. I have some dog probiotics on hand. It's called Total-Biotics by Ultra Pet Products. Ingredients: A proprietary blend of pure L. acidophilus DDS-1, B. bifidum, B. infantis, B. longum, L. casei, L. helveticus, L. plantarum, L. rhamnosus, L. salivarius, L. lactis, S. thermophilus. FOS Fructo-Oligosaccharides(a pre-biotic). Is this safe to give to chickens? Do I just mix in the their water? Can you give to much? Thanks!
