My son's 11 month old Balancer show heifer has gone absolutely crazy. He halter broke her about 4 months ago, she was more stubborn than other heifers he broke, but she finally gave in. He has already taken her to one show and she did fine. About two weeks ago she had an outbreak of warts and we had to call the vet to come out and pluck them. Every since then she has been crazy. When he tries to take her out of the stall to work with her, she just starts jerking, running, and pulling till she gets free. None of us can hold on to her unless we want to get drug through the pasture. When he lets her out in the pasture for exercise, we can hardly catch her to bring her back in. He has a show in a couple of weeks and we just don't know how he can show her, since she is so wild. He can't walk or work with her. Does anyone have any suggestions on what we should do? I've bought some cattle calm, but haven't tried it yet.
