I think I found something....
Mine sleeps in one of those grass tents, and it is only used for sleeping.My only rule is 10 inches of clearance on all sides of the bird. More importantly a very special hand picked perch for their delicate feet. A natural limb on the beefy side (2-3") with all it's irregularities so there are infinite possible positions for a comfortable roost.
you could just use a table stand..We're also debating a large dog crate for a sleep cage for our new Too. We've got one that was used for our Greyhound years ago, so it's huge. The interesting thing will be installing a perch.
I made one for my p'let, very simple!!@Gribouille Oh, great idea! Since the crate is flat and all. I think you're right, that makes the most sense! Thank you!
