One thing most working farms have in common, is land, lots of land. My wife’s family owns Cooper Lane Farm about a mile from our micro-farm. They grow alfalfa for hay which requires a lot of acreage as well as vegetables for their farm stand. People stand in line outside Zoe’s Ice Cream in the summer to buy their famous sweet corn (as well as ice cream of course) The family also raise a few head of cattle.
Chickens and sheep, by comparison, do not take up a lot of space.
