I would take the dead bird in to the state lab To DAY and get it autopsied. It is free. It will also bolster your case in the even this ends up in small claims court, which it definitely would if it were me. Even without you saying who it is, I can only be about 99% sure I already know who you are talking about. Walks like a sick peafowl, gurgles like a sick peafowl, most likely it IS (was) a sick pea fowl. If it is the person I think it is, she is well known for NOT standing behind her product if it is sick or dies. Birds come and go from there like grand central and no way to know where it came from or how long she had it. She does NOT treat her birds ever, for respiratory problems. Live or die is her motto.
