I have friend who for 30 years has maintained a herd of 70- 90 buffalo. He works them like cattle and runs them through welded pipe chutes and enclosures. He NEVER trusts one or turns his back.
Lots of stories, but my favorite is when two youngish 1000 pounds males were fighting in a small pen. One gored the other and lifted him up and over an 8 ft high pipe fence. The other was unhurt and looked around like it was no big deal. But, now out where the cowboys were, they all ran to safety until peace reigned in the pen.
A buffalo ranch near Wright Wyoming had fences that were 15 feet high.
The ranch provide meat for restaurants around the country.
The ranch owner told me that they slaughtered the buffalo before they turned two because after that they had the strength to leap over the fences.
The fences around Custer State Park aren’t that high but pretty close
THAT would have made a GREAT VIDEO !!!
Worked with a lady whose dad raised them. His pasture fence was all welded pipe and corners were rounded.
