Hi, I'm making an aviary and I've heard that ideally you want wire mesh 2mm thick for small birds, (12 gauge), but for a conure which is what I have 1.5mm (14/15 gauge) is good. The only good wire mesh I can find is 19 gauge (which is .9mm thick). Is that too risky/not okay? If not do you know where I can find wire mesh that was galvanized after it was hot dipped?
