I'm so sorry for your loss. Until you (we) get to the bottom of it, you should not try to get another bird. Did the bird come from a pet store originally? What are the ages of the kids involved? Do you know if your son was allowing "everyone" to handle it and pass it around, so to speak? Would you say that is was pretty much tamed and knew how to step up when asked? This and any extra information you can think of to add will help me give you my best answer and advice. Thanks, Patricia
