I'm afraid to see how much this thing really cost. I can guarantee that it was made with less than $100 and a lot of repurposed items.
The hardware wire was purchased last year for a different project that we simply never used. The addititonal wire we picked up from Craigslist for cheap ($8, we still have a huge roll left), the corrogated roof, 2x4s, 2x2s, metal posts and the playwood for the side with the door (it's being held closed with one of my metal posts). The rest was repurposed from when I tore a fence down ealier this year. I still need to build brooding boxes, we picked up some wood pallets that were in decent shape and will be using those. The screws, washers and hinges were in the house when I bought it.
I still need to paint it to make it look nicer and insulate the sucker. It's supposed to snow today (I doubt it but better safe than sorry!). This was built this past Saturday.
