[Marchelo] wanted to build his own chicken coop. He started researching different designs and ended up basing his build on the golden spiral.

In addition to the interesting shape, a ton of clever design choice made it into the build. For instance, [Marchello] took the time to dramatically round over the lumber used as the skids of the base. This, along with wheels on one side, will make it much easier to slide the coop if he needs to move it. Also, the roosting boxes are an addition to the side wall of the hen-house. The roof for these boxes is hinged, so checking on the chickens, or harvesting eggs happens at a comfortable height for the farmer. And finally, the plank that allows entry for the hens doubles as the door at night. So far this is a manual-operation, but we could see some mechanization as a future improvement.
