The first posters link is the same one I copied from for my 7x12 dog kennel/bantam cochin home--am really happy with how it turned, but haven't gone through a winter/snow season yet. Regardless, it's been great so far--just bought pvc (8') and cut it back to 7 1/2 feet, 6" longer than the width (I 'tested' it longer but had too much arch)--found the clamps for chain link at Lowe's (Home Depot had nothing), and put three arches in the kennel. I then covered them with the 2"x4" fencing, and then over half of it I put the tarp I had been using, so it's totally covered with decent wire, then half covered (over the coop and feeder area) with tarp--keeps most of the rain out and the ground underneath is pretty dry. Didn't take days (maybe 2 hours) to figure out, looks great, and working well...oh yeah, didn't cost a fortune either, maybe $20-25 (I already had the tarp and fencing)...peace of mind-priceless.
