Bison are being farmed here in North Carolina. I believe it’s nice meat, but I can’t afford it for a family of (presently) eight eaters, one of whom is a 13-year-old boy who is almost six feet tall.
In the next few years, our consuming population will decline, and the cost of NC-grown bison meat should also decline. Perhaps the equilibrium price will hit in this decade.
It will always be expensive because Bison are dangerous, jump really high so you need a tall wall to keep them in, and they can just push over fencing so you need to build stone walls.
There were several Bison ranches near lake Keystone when I lived in Oklahoma and they were always fixing those walls.
