Doc Harris was right. Grammer gets bad enough on the bords at times that we have a failure to communicate, as the warden in Cool Hand Luke said. At any rate if you are saying that you have tried him in a bucking chute (such as the rodeos have), and he sulks and lays down. Then you have a problem. He will probably continue in the same pattern. This is his defense mechanism. When he knows it works he will use it everytime. A Rodeo producer would most likley not take a chance with him. Due to the fact that he would cause down time. Time is money and the spectators come to see action. Not a bunch of hands working for ten minutes to get a scared bull into the chute. Besides, a bull like that could really hurt people in the chute, not ever knowing when he'll just plop down. With a cowboy on him or while trying to get him cinched. You best bet like another poster stated is to consult a rodeo producer. Even if you are not plannin g on selling, a reputible producer would be willing to share some trade secrets with you.
