Keeping food animals is a possibility, given that my property is fenced with suitable outbuildings. I have sources for breeding stock, and it's nice to have the option, but I wouldn't bother unless I had to. I have worked with food animals large and small, and so have no illusions about the effort and upkeep involved.

I have looked at local "wild" options, and there are many. I can hardly keep the pigeons out of my hayloft. There are white-tail deer running around outside my fence and using my bush for winter cover (I should set out surplus apples in a trough, along with a salt lick). And the grasshopper population exploded this year, chewing up all sorts of stuff. So I have many options for charging "rent" if I so desire.
