Here is a hypothetical question. Say you have no money and can't afford to buy chicken feed anymore. How much land would a chicken need to survive on it's own. By land I mean your normal suburban lot, grass, tree's bushes ect. The reason I ask is because my grandparents had chickens during the depression and told me many times how there was times of no food back then. I doubt that they were buying feed, yet they still were able to collect eggs. So that got me thinking, how much land would you need so that other than when they are chicks the girls would free range al the time and get all the food they need and you would collect all the eggs. Sort of like a closed eco system. Just thinking..don't worry I'm not going to starve my girls!
