The banty side is planned for a trio or quad in each pen. This is fairly generous for breeding pen space, but my banties are Japs, and will have to spend a large amount inside due to plumage issues. Large fowl, unless I add a raised coop area, could have up to six hens and a rooster. With a raised coop area to effectively increase floor space, I could add a few more. Especially where I live, with mild winters, there are very few days my buckeyes, or anything else I have had, don't spend most of the day outside.
