Crun? Roop? For unconventional coops, where does coop end and run begin?

[Mother of Chaos]

As long as the run is predator proof to your satisfaction, nothing says you need an actual 4-solid-walls type of coop. Open aired coops can be open on most of one wall, most of multiple walls, partially wire mesh, missing a wall, etc.

Many varied examples here: https://www.backyardchickens.com/threads/wanted-open-air-coop-pics.1489579/

Thank you for the link! I had seen it long ago (ok, 3-4 months) but forgotten about it.

There go my plans for today!
