We replaced the wheels of our runs with 1,500 lb. capacity Swing-Back Boat Trailer Jack with Dual Wheel purchased from Harbor Freight (they go on sale now and then) and it has made a tremendous difference! They have handles that you can turn to raise the coop, and once the wheel is below the bottom of the run, they can turn in any direction. Now it is super easy to move the runs. Highly suggest this to anyone wanting a easy way to move your runs.
