Well, I'm glad I helped someone.... I'm still considering it for the coop, but I'm gonna see what the condition of the metal roof looks like....hope it works well coupled with the plywood!
That's what really matters to me, the condition of it... Most of what I've been finding for free is falling apart or the old screw holes are corroded\
ipped out, but it is worth it ($$) to keep looking.
Good luck with yours.
