Pikeman I have tons of chickens in a much to small coop. They free range all day and go to bed in the coop at night. It is just wall to wall chickens. As far as how much room they need inside I would base it on roost space. As long as they can all find a place to roost you will be ok. They stay inside on snowy or bitter cold days and I haven't had any casualties from that. Most chickens prefer to spend their time outside except at night. Mine even run around in the rain soaking wet a lot of times rather than getting under cover. I think space is more of a requirement if they are penned up in a small area. JMO
I took a pic of Chopper taking his bath this morning. Just happened to catch it as he threw water over his head. You can see by the churning water he was really throwing it around.
