Sunny (10 months old) started loosing feathers on his/her face about 4-5 months ago and they haven't grown back... I researched this on the net and started freaking out that she (we call Sunny a 'girl') may have 'Psittacine Beak and Feather Disease' because she is really bald between her beak and her eyes (both sides).
I took her to a 'vet' that ended up using a crystal to "sense" what was wrong with Sunny and then I was discouraged ($120 later).
I hoped that it was a normal moult but after reading pretty much everything on this board about moults, I'm really worried.

Can REAL vets determine the cause in a more reliable way? Would it be better to see an avian vet?
I'm so worried for by baby girl... She seems fine and nothing has changed in her behaviour or habits but I know what birds can be like... My 15 year old cockatiel just died one day with no warning

I'll try to upload some pics when my boyfriend's phone is charged up...
