My old business partner 2 years back planted a garden, bought some chickens and ducks, and tracked the expenses. No way was it cheaper then buying at the grocery store. He did have some nice vegetables but the labor and deer control and bug control and watering and weeding, etc. Growing your own is great if you have cheap labor(kids), and a bunch of kids to feed, or have nothing else to do with your free time. I did it for a few years when the wife was excited about it, the deer won, and the potato bugs.
