My wife and I are considering raising bison. She has many food allergies and it is one of the meats she can tolerate however it is very expensive.
All of the local farms sold out of their bison and would not cull anymore this year so in some places you can’t get it.
Here’s an idea, shoot the damn things and put them on someone’s plate!
You might also have try elk as well. Some years’ back there was a pro golfer, (Billy Casper ?) plagued with food allergies, consequently having to pursue a similar diet.
Don’t know where you live, but there’s a host of folks raising bison, some even here in NJ ! Most will butcher and ship frozen meat direct.
As for “rollin’ your own”, I’d say visit some sites discussing that. Those critters are BIG ! And from what little I’ve seen not always respecters of ordinary cattle fencing ! >PS
