Un-expected egg laying
We have a 14 yr old Sun Conure who, for the first time, just laid an egg after building a nest out of shredded cardboard boxes. After all these years, we thought she was a male and has never been paired with another bird. We have heard about female birds becoming egg-bound and the serious health risk that entails.
Our questions are whether or not this behavior is normal given that she has never been paired, whether continued egg laying is likely or a potential health risk, and, if we should discourage additional egg laying, how to go about doing that. So far, we have replaced the egg with a marble of similar size and she continues to attend to the "egg".
