Pastured Pig Hut from re-purposed materials

If you can envision the cylindrical body of a grain bin, then cut it in half, and then into quarters. These quarter cuts are the basis for my Hut. 
It needed stiffening to be highly mobile, so I used repurposed Conduit to bolt sled runners to the side. I added Conduit across the runners to increase stability and to keep it from spreading..
We used a piece of 1" x 1/8" flat stock bolted to the front edge for extra support but it doesn't need it. 
We took off all the supporting legs ladder ECT. I used a 4" grinder and zip blade to cut it apart..... Remember to use a face shield and leather gloves. 
Currently because we're in the middle of winter I'll put a couple tractor scoops of sawdust down under it and then a couple of layers off a round hay bale inside.... face it south and The Piggies are warm and comfy....And best off all I have less than 20$ in two guys .... Not counting my labor of course....
One possible improvement I think I'll try is to add a rough cut oak board floor so they can completely get off the ground... This improvement would be great for smaller pigs allowing us to throw hay on a raised floor where they're high and dry.
