I have a feeder calf it is a carnac on a heat seeker super nice calf but once it hit about 600 lbs it started getting really straight and walking on its toes had a guy out to check the hooves and he said they look fine.and when he stands he is super uncomfertable he just bounces back n fourth on his back legs. Has anyone had or heard of anything like this? anything to fix it? or is it just genetics comments appreciated
