The johnes risk is why I don't own cows or raise calves.  Very young animals should not be shedding it but by around 8 months old they can be fecal-positive and thus shedding it...
Unless I trusted the source herd, I wouldn't run them together. Most commercial dairies have an incidence of Johnes, you should always ask about their johnes status/how positive cows are handled and how calves are handled/fed. Many are fed high quality (raw) colostrum from random cows, and sick tank milk, or fresh cow milk, or milk replacers.
