We turned an old metal shed into a coop. Roof and 3 sides are corrugated. No insulation. It's shaded on summer afternoons after 3 pm.
Floor and front we made of wood. We've been using it since 2015 with no issues. 2 windows in wood side, 2 pop doors, one people door. These pics were of the construction.
That looks great I have a geodesic dome covered my 11 ml tarp been using onto 4 years
thinking by next spring I will need to replace it seriously thinking of a metal style kinda like yours
