Hello, I recently agreed to foster a sun conure. The family that had her said they had taken her in from another family but they didn't have the time to keep her or find her a good home so I agreed to take her in and find a permanent home. She was with us for about 3 days, acted fine, we didn't interact a whole lot because we didn't want to stress her or get too attached. Found her a good home and they had her for about 3 days, said she was very active and vocal, doing well but they came home one day and she was dead. Not sure what could have happened so quickly. Just stress? Did I miss some signs? What could have caused her to pass so suddenly with no signs?
