Okay...I've been watching craigslist for a camper shell or truck camper cheap. I scored big today! I'm getting a really decent truck bed camper....the big one that has the big bed over the truck cab. I'm going to strip it out and turn it into a "Camper Coop". I'm sure someone else has done this. Anyone? What problems did you face? I think it will work great....allow windows that open and close, good insulation in the cold, jacks to allow for keeping it off the ground, shade under it for the chickens...the electric works so I can rig something to allow for light, even in the winter when I need longer "daylight" hours for laying. The best thing about it is that it's cheap, cheap, CHEAP! Way cheaper than I could ever build anything.
