Scratching feathers out!

My Ringneck Parakeet has been scratching quite a bit lately...her feathers are falling out? She seems perfectly fine... does this happen when they lose feathers from time to time or is she getting some illness??? She is about 3 months old now and her cage is cleaned every week so I dont know if there are bugs that they get - like dogs get fleas? Everything else is ok... please post if you have answers...
