Yes looks nice. I think you best spend the money and get some hardware cloth on the thing. Looks like plenty of woods around you, and that means raccoons. Raccoons can and will go through that chicken wire.Sandwiche it between the frame and some trim... UNLESS the chickens are securely locked in at night so even if a coon does get in, it can't get IN.
Other than that concern, it think you did a very nice job on your tractor.
