alt Hacker NewsI asked a farmer once about if it was possible to switch from cows to bison. he said they need a special fence, because they are so massive (and temperamental) that they will just bust through a normal barbed wire fence. Not sure how true it is but seems plausible. I think he said they need a pen that is dug down, so the bison would have to climb up an incline to reach the fence.
That is absolutely true. They are also much more resistant to being handled for tagging or vaccinations. Cattle are docile and compliant, and bison are absolutely not.
