Exploring the pasture
I leave baking soda out free choice in one of those two-section feeders that connects to the fence. Their minerals are in the other section. I believe that they know what they need and only take that. If I were to only give it to them when they're already sick, I'd have to know when they are sick. Who can look at a goat and know that her stomach is upset? Unless, of course, it has been allowed to progress to the point where she's already obviously sick or very uncomfortable. I know no one wants that. My solution is to let them decide what they need and try not to let it get to the point of sickness.
