My neighbor purchased an metal tube, pipe?, shed frame 20 x 30 for $169 and I think it has great chicken run potential! I would like to keep the walls real low, almost creating an A-Frame. I am thinking the roof could be covered with deer netting attached with nylon ties. How does this sound? and the sides could be hardware cloth. I am just planning this but it seems like it would work. I would appreciate all suggestions. I would put the nest boxes/ coop inside the A-Frame for all weather shelter.
