How does Hipps treat the wild horses that he brings in from Texas to sell in Mississippi?

When Hipps arrives to Mississippi from Texas, he has a wagon full of wild horses contained by barbed wire. He tries to convince the Mississippi men that the horses will be easily broken, but as he approaches the wagon, is attacked by the wild horses, splitting his vest. After that, he releases the horses into a pen and the horses run wild into each other and the wooden fence posts, making it clear they need a lot of training.
