We live in the middle of town in a quiet neighborhood. The coop is a shed in our side yard that has a 4x4' gap between the shed and our chainlink fence with a medium sized fenced in yard. We want to let the birds free range when they're old enough. They would be put inside the coop before dark and let out during the day. Is there anything that could go wrong? We have 3 homeschooled kids, two who are older than 15 and they're home most the day. We also have a dog but she's been around chickens and is very well behaved and she's never outside without one of us anyway. Would there be anything wrong with that? Or should we get a run?
