Partner of mine has a bunch of them. Not very old in his herd, nothing over 3-year olds. They have good udder structure at this young age. If you want small framed cattle then the Programs are not for you. They're not huge but big enough. Perhaps not as thick made as I would have thought they'd be or would have liked to have seen them. I'm picking on them a little when I say that. Saw the bull himself and was very impressed by him.
