Until the baby goat can digest the grain, it won't eat it. I fed my kids all the hay and grain they would eat until they were a few months old. By having it in front of them all the time they won't overeat. Since I was raising a lot of kids, mine just got fed milk twice a day. More frequent feedings would have been better but I just did not have the time. As I remember it was 20 oz. per feeding and they did fine on it. I have friends that feed their kids free choice cold milk and their kids do really well too. The kids on free choice milk grew faster than mine, but by the time they were adults there was no difference in size. Mine were full size goats, not minis.
