pleae help!

Question
I adopted a moustache parakeet about two moths ago. The previous owner brought it in to "Petsmart" and abandoned the the bird, so I took him and gave him a second chance. he is about 2 years old, very sweet and playful. He gets a lot off attention and he seems to be happy about it. I couldn't have asked for a better bird. However there is one BIG problem. He wont stop plucking himself and I'm loosing hope. I don't know what to do. I bought him a lot of toys so he'll have have something to do when I'm not home. I give him baths, feed him a balanced diet consisting of bird food with includes pellets and seeds. I give him plenty of veggies and fruits, some nuts. And he still wont stop plucking. His chest, neck and parts of his back are starting to develop bold spots. I don't know what to do. I need advice. Please help us.
Sincerely,
Evelina

Answer
Evelina,
These questions seem to be coming in from the bird section but as I stated in my profile I don't know much about birds. I suggest you re-post this in the bird section. Other than that I would call a vet that treats birds and look it up online. Just Google parakeet self plucks feathers or something of that nature.
