Hi
I can't answer your question about if her droopy wings will improve but I guess they work well enough if she can fly. Sounds to me like you are probably right, its the early confinement in a small space that has led to this. Living in an enriched environment, getting exercise and not getting bored is what birds need. I think you are giving her the best possible chance to improve and she does sound very happy anyway, even if her wings continue to droop. A month isn't very long so give her more time. You could get a vet to check her over, especially if anything changes.
