My sheep didn't think much of the garlic bucket i gave them last year. However, they love it when I sprinkles garlic granules on top of their general lick bucket. So now I just do that from time to time. They also loved the seaweed powder/granules which I gave them in the same way. I think if I could come up with a decent design for a mineral feeder that would keep stuff dry and is easy to move, I'd have one with three compartments - garlic, seaweed and rock salt. And then ditch the licky buckets.
