Hello - I have 3 male nigerian dwarf wethers and one female dwarf. We currently feed them Purina Goat Feed 2xday and also alfalfa and timothy pellets. I just got some chopped alfalfa - is this safe to feed the wethers if we only do it once a day or is that too much? I can continue the timothy pellets and do the chopped alfalfa instead of the pellets, they seem to prefer the chopped but had one of our males already pass a UC stone and he was in HORRIBLE pain - don't want to go through that again! Any advice? We do have minerals and I give them baking soda not sure how often to do the minerals do I just put it in their food?
