IMHO we worry too much about floor space and not about roost space. As long as your birds are allowed out and then free-ranged there should be plenty of room for 21,. However, if I were you I'd add another 12 feet of roost space. If you don't they'll be roosting in those nest boxes and they;re a pain to keep clean. I wouldn't add any more though--something that is hard to do.
