4. Round-Top Mobile Chicken
Once in a while, one of those projects that show up are not originally DIY works but look very much so. This is sometimes because they are hand made. The good thing is you can reverse engineer it or break the rule and purchase one of these for $399.00 basic model and pay $49.00 for each extra feature.
The Round-Top Mobile Chicken Coop has vent-wings which open and close depending on the conditions of the weather and a Run Door with a latch which is Secured by Positive Gravity. It is built with North American cedar.
