AlpineMom,
I'm glad I'm not the only person here without pasture! I'd kill for 5 or 10 acres, but here in farm country it's just not going to happen.
I feed a variety of animals together--5 llamas, 2 alpacas, a small flock of sheep and my goats, so I put out a gazillion feed pans, and mix all stock sweet feed, Cargill Nutrena lamb and kid feed, beet pulp, and BOSS. THere is a small amount of corn in the all stock, but I really don't think it's enough to bother my rams or wethers.
I use a mineral mix made by Buckeye Feeds, keep baking soda out free choice, and they have a round bale of alfalfa/orchard grass hay that they have access to at all times.
It's a little bit of a dance to make sure that the goats have enough copper, and the sheep don't have too much.
