My
Aviary
My aviary is attached to the side of our house.
I can walk from the house thru a door into the aviary which makes it very handy.
It is 8'x12' with 9 breeding cages, 2 - 24"x16" juvenile cages.
A 3'x3'x3' holding cage and a 4'x3'x3' flight and a 9'x3'x3' flight.  As you can guess space is at a premium, never enough.

My breeding cages, the nest box's are a box in a box, I built.
4' flight and 2 juvenile cages
My 9' flight, hospitial cage on the self
3' cage and some what cluttered shelf
