My 4-H steer is giving me some problems lately. He stresses anytime I try to work with him. He's been in the chute and is fine with me petting him then. I manage to get him tied up, but when I come to unclip him, he pulls backs, the whites of his eyes show, and he just freaks out. The only time I can pet him out of the chute is hen his eating and even then, he sometimes still freaks out. Any advice on how to get him calm down? I don't want to push him to much, he has already lost some muscle. Any advice would be great. Thanks.
