I'm sure that the reactions and posts will be in strong favor of hardware cloth, but I'm concerned with cost. I live on the east side of Indianapolis, and other than the occasional 'possum, I haven't seen any larger predators (raccoons, weasels, etc...) in the area. Using "chicken wire" would be substantially less expensive. I am attempting to build my coop/run with the only cost being the wire and hardware. My plan is using a deck/railings I tore out this spring and pallets for my lumber,and hopefully snagging a few free shingles or a sheet of metal roofing for the roof from my father who's a carpenter and often has some leftovers from jobs. Am I just being a cheap bas#$%? I've seen some runs made from pallet lumber that are about 3 ft high. I'm assuming this height would be sufficient since chickens on the whole aren't all that tall. I also thought about using plastic conduit and making an arched run on the side instead of a square one. Again, more cost, but would probably be pretty easy to construct. Also, I keep reading mixed ideas on insulation. The coop will be facing south with the back wall against the northside of an unheated garage with a run under the coop and around the east side of the garage. The whole operation will sit on a raised bed that is 2 1x10's (approx 18 " high) in same location. What kind of insulation, styrofoam? batting? I'm assuming it would need to be sandwiched between 2 layers of lumber no matter what. I just want safe and healthy chickens while not breaking the bank building my coop and run. Any suggestions and ideas? Yes, I've checked several of the forums, and if anyone knows the ones I should double check, let me know. This will be a spring endeavor along with building some raised beds and ammending some horribly gravely "soil" in our garden. I thought I'd start by making plans/gathering materials before it gets too cold out there.
