We had a bull that was super gentle and had broken his penis..... Best homer ever. Lead him into the cows, let him check, lead him out. If he happened to get one stuck it wasn't a bad thing, about half the time we were AIing to him any way...... He took feed but he earned his keep in lots of other ways..... Heifers out, go get him, lead him out there and the heifers would follow him, he was a pet, and a very convenient gomer. Never took more then five minutes to find who was standing.
