Just wondering how many hens could fit comfortably in a coop that is 4x6 with a much larger outside run IF they will mostly be free ranging and just going inside at night? This is something I am confused about since I have seen some 4x4 pre-fabricated coops that claim to house 4-5 hens? (And 4x4 was the entire thing - coop and run.) How big is your coop and how many birds do you have? Thanks for any input!
