Honestly I think that space becomes a bigger issue if they are confined to a run during the day as well.I have a 12 x 7 coop that has laddered roosts.I currently have 41 birds in it at night.They don't even USE all the roosting space!I have 2 empty roosts!BUT with that said...they have a lot of space outside(free range on about an acre) and during the winter we shovel areas for them to roam...My hens are never in the coop unless laying...or roosting.Even in the rain/snow they prefer to hang out UNDER the coop rather than inside.I have no pecking issues so far..and it's been over a year.This is season 2 for them.
I have not had any issues due to space with mine.My coop is well ventilated..has a TON of roosting space in different areas and plenty of nest boxes.
I would say to go by your chickens behavior and use the actual footage as a guideline.Just my .02
