I got an incredible deal on one of those cheapo put it together yourself kits and then we went to Home Depot and got wood and made an addition, which is basically a box on stilts with a large door and 2x 2 roosts. It's been working great for 7 years and I live in New York, and gets freaking cold here, frost heaving etc. Ee buried wire under the chicken coop which was set up on a frame of 2x4s. The back addition was made out of cheap fencing posts...not posts, the flat ones...at Home Depot the cheapest wood they had, and I painted it with some Barn stain. Added vinyl flooring leftovers from our kitchen some white whatever kind of paint that I put on the inside, just to make it easier to clean. You can slap together something yourself that'll be perfectly functional and won't cost an arm and a leg if you have basic tools and a power saw or strong arms. I have almost no knowledge of construction and we made a really nice chicken coop and a huge run (welded wire walls for run, walk in human sz door, and wire over the top with a black mesh shade tarp *roof*, no experience, way cheaper than the custom (amish) ones sold around here.
