Shelly's problems aroused my curiousity as to how much time ranchers with large cowherds spend on problems such as hers, (stupid calf won't suck) a cow or heifer not allowing a calf to suck, working with twins, or getting a cow that has lost her calf to accept another one. Does it make a difference as to whether it is at the beginning or end of the season verses in the middle when calves are coming fast and furious?
