I would go insane being slowly surrounded. One of my donkeys came from Nevada. Don't really have nothing to do with nothing. I checked my trusty goat books and they do mention alfalfa hay and pellets, so if it's working for you go with it, I'm not a personal fan, I don't think it should make up too much of the diet, but I'm not a goat God, I just know how my goats do on what I feed them, and how rich diets are not good for an animal that evolved to consume a poor diet. We all have to find what works for us, and I still think your goats look fine, they will fill out as they age.
