That all depends on your wether! I have one who gets fat, seemingly on thin air. He really only needs hay. I have in the past given him a small handful, literally 10 or 15 pellets, of a pelleted goat feed. But that was only to keep him from feeling left out when I gave the others their feed. I would tie him up, to keep him from stealing from the other goats. Now he is in with my buck, and no longer the top goat on the pecking order, so I don't have to worry about him stealing when I give my buck his feed ration every day. They get mixed grass hay, nice quality, as much as they can eat before the next feeding time. I was feeding an alfalfa mix, but got them off of that as soon as I was able to buy some different hay, since I want to save the alfalfa for my does. I was also worried about creating a calcium imbalance in their diet, since my water is very hard, with lots of calcium in it. I have never had any issues with either calcium or phosphorus stones, though. At least, not yet! (Knock on wood)
