I have two boers, 4 and 6 months old, two pygmys, about the same ages, and 3 nubian kids, about 6 weeks old. I feed them hay and I feed them 16% textured dairy goat grain. The kids get free choice, and the 4 others get about 2.5 lbs total, twice a day. Thus far, I have given them no supplements. I bought a mineral block but they don't touch it. They seem to be doing fine, but I have little experience so I don't know if they are growing as fast as they should. Should I be doing things differently? I assume there are minerals in the goat grain but I don't know if that is enough. I have a friend who feeds yeast to his goats every day, but I'm not sure why.
