A few years ago we bought some heifers off my dad's buddy. At one of our farms, we have to move the cows between pastures every week or so. The cattle love the fresh grass, so they usually run to the new field. However, Everytime we tried to move them this heifer would lift her head, take her calf plus 6-8 others to the back of the pasture.
It was decided we couldn't have this cow teaching everyone bad habits. Same deal, maniac level chithead in the corral, escaping etc. We barrowed a dart gun from a neighbor and walked it on the trailer like a drunk puppy.

We sent a group of old, big bodied cows who raised their last calf directly to Cargill. It was a before Christmas, they averaged just over $400. No animal is worth getting hurt over, but definitely not for that.
