Can I comfortably fit in a coop that is 6'deep 8' wide 4' high in back and 5' high in front? we are wanting to start w/ 11 pullets and 1 roo. Also, would 3 nesting boxes be fine. How big should our temporary run be? (Just for the adjustment period.)We aren't planning on getting them till next year, so we still have some time. I just don't want to wait till the last minute to figure all this out.
