Also, they are very happy (sometimes, and some birds) with plain old cardboard boxes. My two tiels will not use a nest box, ever, but love shoe boxes. But then they are a bit strange.
yeah i saw how people were using cardboard boxes. i thought about and i think since they will be in an outdoor aviary they would not be the best. dont want them to get wet. i think i may just have to get them at a local bird store
