no idea where you're located but round here (upstate NY) there's several buying stations for slaughter that sell bob calves to the Amish and others to feed on, local salebarn also has a regular bob calf sale every wednesday. If there's any larger dairies near you then you may be able to deal direct with them, would certainly give the calves a better start and less exposure to outside pathogens. Price round here atm is $50 - $100 ea for holstein bull calves.
