Thanks guys. It has made caring for them much easier. Though I still have to keep the larger parrot separate from the smaller guys.
did u seal all the edges, bases and corners as to protect domesticated bird from domesticated Cats.
While it is all sealed my cats actually pose a much smaller threat to them than the local chicken hawk and falcon. So the roof had to be able to withstand their break in attempts without hurting them as they are protected. My duck keeps the other cats out of the yard.

I was pretty floored by how well he does. People at the bird farm thought he was to big to be just a duck. He stands 2 feet tall bill to tail and outweighs all my cats.
The wall he's peeking over here is a 20 inches tall and he's down in a small drainage ditch
