Good to know. Would you go 16 or 14 gauge? Or something else?
Should have plenty of ventilation.
19 gauge should be fine in most applications, however if you can afford 16 or 14 that would be thicker wire that should offer more protection. For the predators you have listed: Coyotes, opposums, skunks, fox, raccoons, hawks,falcons, bald eagles, etc.... 19 should suffice as long as it's well attached, with the caveat that it's been proven that very determined dogs (and of course bears) can get through almost anything.
