We have a heifer this time that is really nice. She is out of a cow that is admittedly a little on the nervous side. All of the rest of the calves don't pay you any attention when you are walking through them like we all like them to be. However, this one calf wants to keep her distance and will retreat whenever pressured. How are the temperaments on Unstoppable calves? Does he seem to improve attitude and disposition or make it worse?
