I made it out of old 2x4s from a shed I tore down a few years ago. It has a top area that provides shade over the nest boxes and can be raised on hinges to allow me to collect the eggs and get the feeder and waterer for refilling. The way I made the wheels be able to raise and lower the tractor works much better than I was expecting! I have 2 handles on the other end and it's a simple matter to lift and move it. Here is how the wheels work. Down Up!
