I do, DH was raised that way. Now his folks both have jobs, and the farm is more of a hobby. But they still have about 50 head of cows and it pays for itself if nothing else. Dh and his BIL spend every weekend over there working.
But I do think the guy on that website said he had a "city job" as he put it, that he does also. But I am not sure. I know I would probably get kicked out if I did everything he does! 50 chickens is pushing it!
