Goose-lynn passed away. When she started showing those symptoms, I knew that she wouldn't make it. She lasted for about 9 hours after that was posted.
I was worried that it was because of her strange navel, so I talked myself into investigating to help save the other gosling. Believe me, it wasn't easy to do. I loved my little Goose-lynn. Upon my investigation, I realized that what is going on with their navels seems to be harmless and I'm fairly sure that it won't affect Gooser in any negative way.
I believe that Goose-lynn died because of an absorption problem. I found a full sized yolk sac in her body cavity even though she was over 3 days old. She most likely died due to the lack of nutrition...
Gooser is very healthy, though he cries whenever I'm not there next to him. I need to find him a buddy. For now, he talks to a mirror that I put in his pen and he sleeps snuggled up to a small plush cat.
