Supplement tub or block for llamas?

[aspentrax]

Hi. Is there a supplement tub or block I can give my llamas? Also how do you worm them? Thank you.

We have not found a block that does not have copper in it for our Alpaca so we use loose minerals from Stillwater Minerals. They have a Llama mix and an Alpaca mix.
