So sorry to be reading this Marianne. It is not a lot of consolation, but remember that without you Charlie would never have gotten to experience the joys of flying. He may not have been with you so long, but be happy in the knowledge that his life was improved by coming to live with you.
Rest in Peace, dear little Charlie.
We are not Vets, Avian or otherwise. If you have any serious doubts about your budgies' health an appointment with an Avian vet should always be your first point of call.
This is a very sad news Marianne. I am really sorry for you. Rest in Peace, little Charlie.
