The problem is that you will have to figure out what works for your farm. If you have no pasture, they will need hay. Whether you figure out how much they eat in a day and only put that much out or have the hay full all the time is up to you. As far as minerals, you buy the best one you can find. You can always supplement. Alfalfa pellets are always something you can feed. Then depending on what your herd is for will depend on what feed or not you want to give. Again you will just have to find the best local feed. Keep in mind something like Purina Miniature Horse and Pony can also work along with a goat specific feed.
