a wood coop isn't warm at -17f eitherI personally don't think chickens would be happy in a coop that won't stay warm (hence the wire walls) have you thought about predators???
the cattle panel is the frame... it's covered in Hardware Cloth with a HC apron, then covered in 2x4 field fencing, then clear tarp https://www.backyardchickens.com/articles/mos-cattle-panel-hoop-coops.73385/
