Hello! I just moved to Idaho, and I have my landlords permission to build a chicken tractor to wheel around his empty pasture, but I gave my chickens away/sold them as I didn't think I could keep them. All I have left is my 6 runner ducks at my sister's place. Portable duck pen ideas, anyone? I was thinking something along the line of a chicken tractor, but it needs to be bigger as the ducks are going to be in the pen all of the time. It also needs to be lightweight, so wood frame for the run is not ideal. Suggestions?
