We're moving our chickens into a barn, which will be our new coop. I've forgotten the exact measurements, but it is probably about 10' x 20'. We don't plan on having more than around 30 chickens (5-10 would be bantams or half bantams), but I can see us having a few over . They will free range from the time we get home from work (varies, but could be anywhere from 2pm-6pm) until dark. On weekends they free range all day. How big would you make the run? Although I want my chickens to have plenty of room, I don't want to build/upkeep an enormous run that isn't "necessary", since they do get free range time. The barn is also right next to another barn, a road (ours for tractors/trucks, not a highway or anything), and a hill, so the logistics of a huge, long run might be a bit difficult. On that info, how big would you make yours?
