So here's my project. I'm going to try and build a chicken tractor and raised garden beds in tandem. The idea is that the tractor will neatly fit over the raised beds or be able to be used on it's own. Has anyone done this? I'd like the tractor to be light enough that one person can move it too. I'm leaning toward 5X5 squares with a chicken hut on an upper story. Any thoughts?
