Way too much milk replacer powder per amount of water unless the scoops are small. Most milk replacer calls for on measure "cup" that is provided in the bag, per 2 QTS of water. Look at the directions on the bag and FOLLOW THEM. A qt is 2 pints so a normal size calf bottle is 2 qts or 4 pints. If you are using the cup that is provided you are giving it more than twice the powder needed. It sounds like the calf has been getting milk that is more like liquid pudding. Are you giving this calf free choice water to drink? Also any hay? The calf needs fresh water at all times in front of it.
