forget the chicken coop. I'd clean it up, wire it up, plumb it up, and make a "hatching hut" out of it. We all need a chicken haven to retreat too.... I'd put a couch and TV in it too for when I want to escape the pressures of the real world!
Admiration... jealousy.... wow! Great find and you can do as little or as much as you want to it. Altho, a couch and TV might make it a little too cozy... Enjoy, and be sure to post pics when it's occupied by chooks.
