To me it looks like a regular moult, sometimes the feathers get a bit dishevelled like that and there is nothing to be worried about because that misplaced feather is about to fall off and be replaced by a new one. Over the years I have had at times a few budgies losing both the longest tail feathers in a moult.
Also the primary flight feathers are there while some seem to have been clipped, if she were to lose all the primary flight feathers and the main tail feathers shortly after growing them and on a consistent basis, then it would in fact have French moult.
Her overall appearance looks very good.
She's a very pretty bird. She looks like she's having a regular moult to me. And, I have a budgie whose tail feathers came in like that. They were gone on the following moult, but he does still have a "curly" chest feather.
Thanks everyone! I was worried at first and didn't want to bring home a bird that could have a disease, I appreciate you all confirming my fears were not correct I have seen her stretch her wings several times and, although she was clipped by the store, she does not seem to be missing any flight feathers, and none of them (even the stubs) look disheveled! She does have pin feathers on her head so it definitely seems to be a molt
