I work on a small farm that sells vegetables near Chicago. We're interested in converting the old 15x7x 6 farmstand into a chicken coop so that we can sell eggs. I don't know where to start! There is so much information to sort through and I honestly don't know the first thing about raising chickens. Any hints and tips, (and even better, step-by-step beginner's instructions), are appreciated. I'm vegetarian and very concerned with making sure the eggs we would sell come from humanely raised, happy chickens. Thanks.
