I agree with stress bringing on worms but would argue that goats should always have access to baking soda and loose goat minerals. I am no expert but have been lectured many times by experts on that very subject. They know when they need it and how much they need. They will lick it up greedily. I know mine do.
Your does should be fine. Just be aware that while their requirements are similar to sheep they do have different mineral needs. Most areas in the states have mineral defiencies so the browse doesn't give them all they need.
There are several great books on goat care available.
