The place where I've been thinking of building my coop (erm..ok..having DH build my coop) is beside a deck. The deck is just over 5.5 ' from the ground, and I'm wondering... since it has posts every so often, and has a floor...could I just continue to enclose it underneath with hardware cloth on 3 sides (the 4th side is house) and use it as a run? The floor boards (which would be the roof of the run) are about 1/2 " apart. Since most of the structure is already there for a run, does it make sense to use it? What would be any downside?
