I am expanding my flock, and am trying to decide if I should do 4x8 coops or a small barn divided with and runs. I have not really done the math yet to decide which is best. I would think it would be easier to clean one large area, and easier for me to lock them up at night instead of counting heads and locking up 4 different coops. Which is more cost effective 4 4x8 coops or one say 2ox20 barn?
