This tractor was made with three 2x4's a few pieces of PVC, some screws, and chicken wire. Thanks to zip ties and some scrap lumber the door was made. Chris, Miriam, and Keenan helped (with Chris as project leader) and it took us about two hours form start to chickens inside. I don't have plans to share but the idea is simple enough. We faked it awesome. It's a 4x8 wooden base with PVC pipe hoops covered with some chicken wire. One end is covered with a plastic tarp for weather protection. Right now about thirty nuggets are inside but over the weeks ahead we will build a few more and the plan is to have just a dozen or so birds in each, on pasture, up on the hillside where the sheep and horse have been grazing. Joel's taught us all how herbivores should be followed by flocks of birds (just like in nature) and that is the plan on this farm!
