Honest advice... don't mess with any kind of stock. They take fences, feed, vet attention, a trailer to load, pens, ropes/gear, water tanks/pipelines that don't freeze or dry up... list is almost endless....even for the experienced...and, if you had a lot of experience, you wouldn't be asking the question. Enjoy your acre..and, if you absolutely MUST have something to mess with, try chickens, cheap in, low outlay in facilities and you can walk away without having spend anything more than a small fortune. In any case, you'll NEVER "make money" on any legal livestock/crop on 1 acre, but you can be RICH in enjoying the place.
