Back on the ranch, I was sleeping one morning and heard the loudest tin banging I had ever heard before. I went to investigate ......There was 2 Charlois Bulls inside my chicken pen fighting. They had broken the gate to get the feed. There was about 5 feet on either end of them to the fence, every time one would push the other that big ole rear end would just obliterate the posts and wire. It was a hot mess! Sorry about your troubles, good fences make good neighbors.
