Raising chickens the old-fashioned way is the best way! Free-roaming chickens that can feed on bugs, plants and feed in a chicken yard are the healthiest, have the healthiest eggs and make the best meat (sorry if you're a vegetarian!). I won't even eat chicken from chicken factory farms (see more here). I was going to draw that too, in contrast, but it turned my stomach! Actually most old-fashioned farming methods are healthier than modern ones.
