I'd still opt for majority mesh with wind breaking panels to be easily applied as needed. Heat is really hard on the birds. Maybe something like this interesting open front hot weather coop https://www.backyardchickens.com/threads/open-front-coop-done-chicken-yard-in-progress.1160614/So I think I'm going to skip the whole wall idea and do a half wall leaving it mainly open to the run. Just saw a coop down the street and it was completely open with a little 3 sided covered section at the end.
I want to at least put a half wall up though to protect from the wind.
Any thoughts?
Thanks
