I'm so totally confused. I have two bucks (will be wethers in a few weeks). They are still on the bottle but I'm researching what to feed them after they are weaned. I've decided I will not feed grain, but what about alfalfa? Half of the people say no alfalfa, and the other half say it's fine. Also, how do you know if the grass hay you get is good quality? And everyone is saying to find out what your area's calcium, phosphorus, and selenium levels are....how?? Where do you go to find that out? I'm in southern Oregon btw.
