He looks like a plucker, but the cause of that could be many reasons. A lot of the times, that can be cured, if it hasn't gone on too long. I would easily spend the $400 just to rescue that bird, I wouldn't care about the vet bills, he needs to be put in a loving home where he can get the care he needs. Thats all that matters to me.
Give the poor guy a chance....:dry:
