I have a gold sex Link that’s is about 18 months old. She has been laying soft eggs with a tail for few weeks. Prior to this she laid one egg almost daily with no issues. I find her a with a weird soft shell tail hanging from her vent. I’ve helped her pass them my gently pulling on the tail. 7 other birds have been laying just fine, no weird eggs. They have crushed egg shell, oyster shell and layer feed. I took her to the vet and they said she was healthy looking, clean and everything appeared normal but gave me some antibiotics just in case. Attached are pictures, one egg I popped because I wanted to see if it smelled or was rotten. It seemed normal other than the lack of shell. I’ve seen this topic a few times, but never heard the fate of the bird, any insight would be appreciated
