Only thing I have to disagree with is when you said chicken wire is useless against weasels and other predators. I agree that chicken wire will not stop small snakes, or things like bears or mountain lions it is sufficient for 90% of predators. I have used it all my life and my family for as long as I can remember and longer. We have hawks, owls, eagles from above. Weasels, coyotes, raccoons, foxes, bobcats and the occasional wolf. Dogs and cats. If it's built properly it will be just as effective and much less expensive.
