I am planning on building an outdoor aviary for my Macaw and Eclectuses and was wondering if anyone has done this? I've seen a few but none of them seem big enough for them to fly very far. I would like to build it to be about 15' by 30' maybe. Even bigger if it's not outrageously expensive... I'm having a hard time finding a supplier for as much material as I need without having to order way more. I like the zoo mesh but I can't even find prices for it. If you have built one, I would love pictures and prices would be great. Thanks!
