We think we may have a miniature jersey cow and bull. We purchased them when they were 2 and 3 weeks old as regular jerseys but they are very small and are now over a year old. We read that a mini jersey bull is 43 inches at the hip. We aren't sure whether we should measure him to the backbone or to the top of the hip. He is 48 inches at the top of the back bone but is about 43 inches to the top of the hip. Does anyone know? We will be thrilled if they are miniatures. Are they considered full grown at 14 months or is it possible that they will get taller?
