Hi, Here is a picture of a little chickens tractor I built about 2 years ago for grandson in Atlanta. Simply used two old lawnmower wheels that I had. Got two carriage bolts the size of the bushing(hole) in wheels. Drilled holes in lower frame work of coop, put bolt thru, then tightened the bolt to the frame work with large washer and nut....added another washer, then wheel and finally nylon insert nut to hold wheen on. Pretty simple....then ya just pick up other end and roll around like a wheelbarrow. Good luck.
