How much AC should I be giving my two ND wethers. They share 1/4 cup of grain in am and 1/4 cup in evening and alfalfa/grass mix hay. Right now I put a 1/2 tsp on their morning feed. Sometimes I notice it doesn't always stick to the feed completely. Should I use molasses to make it stick? They are about 6 months of age. Also Do I need to increase the AC as they gain weight? These stones they can develop scare me Help, please!
