I have a Rhinehart X50 that I purchased for my goats. It has a removable goat tip. If I remember correctly, it can be used on calves. Disbudding was my most stressful and most dreaded chore but if I considered it important for kids, I consider it even more important for calves. Would this iron work well for calves? How are they restrained? What I would rather do is to breed to polled bulls. Will a Jersey bred to a polled Angus always have polled calves or what is the percentage? Thanks!
