A farmer I know has a Charolais bull. He has produced some nice calves since the farmer has owned him. Lately he has been doing something new. When the farmer takes the bale out to feed, the bull began to round up the cows and calves, just like a herding dog. He would butt the bale hard before it was dropped from the spear. Last night, he only rounded up the calves but waited till the bale was on the ground to start butting it. The cows seem to watch him closely to stay out of his way. The farmer is thinking it may be time for him to go to the sale. Has anyone had a herding bull before? What would this behavior mean?
