Hi all! I'm feeling confused about how many chickens would be ideal in my coop and run. It's an 8x8 coop, with large windows and vents. There are 10 nesting boxes tucked into a bump out. It opens to a run that is 6x12. We plan to free range them when we can. The company we bought it from said 10-12 chickens in one place, and 15-20 in another. We would like to keep as healthy a flock as possible. We are in northern Illinois so it gets quite cold in the winter and quite hot in the summer. Any advice is greatly appreciated!
