We get the chicks in the mail as day-old birds. We use a design for the brooder house from an old war-era extension office booklet. It shows how to make a low-cost and super effective brooder area out of plywood (since metal was so scarce during the war). They stay in the brooder house till they are about two weeks (their "teenage" years), then they move out to the pasture to get bugs, grass and feed. They LOVE the grasshoppers, and they help fertilize the fields in the process. They're only cute for about a week, but they're super fun for the kids!
