What would be a good coop and run size for 4-6 banties? I am expanding my mini flock and am building new. I lock them in at night. I also nedd something on the smaller size because they are hidden. The current coop is hardly noticable because it's painted a dark green that blends in with the pines nearby. i don't allow them to free range but the current coop/run is moved around all season except for winter when I keep the 2 I have inside.
