The bison are fairly wild, so you can't really help them when they get sick. Once they finally let you close enough to help them they usually are so sick they end up dying. It is not the everyday work that is the challenge, the big thing is starting out - getting fences, picking roots and burning roots. I'm finding it to be more interesting than logging. The best thing is that it gets me away from stress of logging, and a farm is a good place to raise children.
Buffalo take care of themselves, even in calving.
The worst thing about farming is everything I do means more money. I haven't really made any money on the farm, maybe in another ten years. If you want to farm, start with a big bank account. I don't know if it will be the right way to go yet. Do not mortgage your house to farm here, start slow and see how it goes . . .
