For the last year or so I have had a budgie die every couple of weeks, they have been all ages. It's always been only 1 at a time that gets sick never more than 1. They fluff up, lose weight & energy. They continue to eat & have a lot of fesses around their vent. It usually takes about a 4 to 5 days to die from when I notice their sick. The birds are divided into 4 aviaries & it is random where the next bird will fall ill. Any ideas??
