Amazing story about how neighbor wanted payment for putting cow into trailer not attached to pickup, then breaking leg.
Interesting comment re electricity and horns... all I can say is that make sure that you have a fence charger qualified for 100 miles... 200 is better... they are at TSC... Not sure what you will do since horns can rip out barb wire...
Hmm... buffalo.... I gotta be honest with you... I gotta recommend you leave them alone.. I have no personal experience, only personal stories from people over the years. My belief is that they are COMPLETELY different animals from regular cattle. They can become vicious in an instant, will test EVERY fence, enclosure, whatever, and are strong, strong, strong. They are simply wired differently from regular cows. I doubt, strongly, that you can handle them with your current equipment and frankly fear for your safety. Somebody who has personal experience with BOTH animals may be able to refute my beliefs, but I believe they are realistic.
