I am wanting to get some free range chickens in order to keep pests away around my house mainly and also in the yard. We have six acres and I was thinking I can build a coop only (no run) and let them free range and hopefully come in at night. So, my questions are this. Is their a particular breed that tends to stay close to the house and not roam as much? Should I leave them in the coop/pen for a month or so so they know that is their home?
