I have a chicken coop with chickens. I have a house with their own room for parrots. I don't know what part of the country you live but I live in a pretty mild climate. I too have an outdoor aviary. My outdoor aviary was built by my husband with an existing canopy. The screen, metal frames (no wood as things can chew through, including our parrots) are outside and inside. On top of that, I have heavy heavy plastic clear curtains that velcro in the exists plus a bird safety net. With this in mind my aviary is 12 x 12 with a 12 foot ceiling. This whole thing is covered. There isn't a centimeter loose and we must check it after every storm. We keep two professional heaters (think restaurant style) and two Stanley shop heaters to use during the winter and we live in mild temps (we go below freezing once or twice a winter). In the summer, my canopy sits under a tree and again due to the climate we get cool breezes from the ocean. On hot days, we have two coolers, one is a swamp cooler and the other is a portable cooler, plus we keep a large industrial fan to circulate the air.
My chicken coop is five feet tall. It can hold up to 10 chickens. I keep just three as pets. None of the coop is safe for any parrot that I own. If I wanted something other than chickens out there, I may do quail or some other outdoor wild bird that doesn't fly. Our coop is two stories, the bottom has their food and the top they sleep and lay. I give my chickens fresh veggies, dark greens and the same stuff I give my parrots sans citrus fruit, plus their mash, grit, oyster and scratch. I bake homemade bread for them to eat every day and I give them fresh corn on the cob no matter the price as the love it. If I have to I will buy frozen and give it to them.
No parrot I know would be okay with any of this. If you want a bird, buy a bird cage. It's safer for the parrot. Otherwise your parrot will become a very expensive tasty meal for any creature that lives outside, including cats, dogs, raccoons, possums, etc.
