The hens need more room! And I am in *Use What You Have* mode. What I have is leftover metal framework from temporary canvas carport: the canvas has decomposed and blown away but the metal tube frame is still sound. I thought I would erect some of it inside the large henyard and cover it with a combo of hardie siding 4x8 panels (on the side that takes hard weather) and clear or translucent wavy panels on the sunrise side. (Already have a few of those in re-usable condition). The fitted canvas covers were attached by bungees and heavy duty velcro straps, so the tubes have no holes in them. Coop does not have to be predator-secure as it is already inside secure henyard. Has to withstand high winds. Any ideas? TIA.
