Okay so we have 5 chickens right now, we used to have 6 but our 6th one was a roo and thus made a magical journey to the stewpot. We want to have at least 6 chickens though. We have enough interior room for 6 chickens with 3 nesting boxes. And we have enough exterior run room for much more then 6. We also free range them almost every day (we never let them free range if we're gone.) As I said, we want more chickens, However we can't just raise a single chick and would need to have two before we introduce them to the rest of the flock, can we have 1 chicken more then the ideal interior square footage per a chicken if we free range them every day?
