What do you do if you can't get your goats to eat their minerals? My two won't touch it if left out free choice. I've tried mixing it with their grain but they somehow manage to eat all the grain & leave the minerals behind & turn their noses up. They act like a three year old with a plate of broccoli! I know from what I've read here that loose minerals are generally preferred, but I was thinking of trying one of the flavored mineral blocks I saw at the feed store instead.
