I would highly recomend that you 1) Halter break him , but do NOT make him a pet. 2) castrate him as soon as possible. My across the street neighbor got a free bull Hereford calf that was abandoned by it's mother at birth. He castrated him but made him into a pet. A year later this calf is just too big and really has no respect for it's owners. He throws his weight around and/or butts everyone. Now, he has to bulldog him down a couple times a week to show him who is really the boss of the barnyard. The neighbor can't wait for processing day come Jan.
