Hi. I had bought a female budgie from the pet store about two years ago and sadly she past away today at 3pm. We were getting ready to take her to the vet but we were to late. She's been fluffed up for two days and wouldn't eat anything but my other budgie kept feeding her. I thought she was just tired because she had an egg and she would always be tired when she had an egg. I just wanted to know if she died from an old age or a health problem.
