Well she's up and about. Not really flying yet but lively enough, so she'll pull through I think. No need to see a vet.
I've put her in a smaller cage in the aviary so she can be around her budd(g)ies

put with acces to her own food and water.
I don't know what happened, but if I would have to make a guess, a night fright is exactly what happened.
We do have some cats in the neighborhood...
