What is Sally? Jersey? The mooing is normal I'm pretty sure. DId you get her to milk her? If so I would go ahead and milk her. Why not? I would! You could also turn her into a nurse cow and let her take on one or two. But you can't just toss it on there yo uhave to teach her to take it and on that I'm not sure how to do. Never done it only read about it. Anyway best of luck! Keep us posted!
