Good idea Barbara! Sending photos to a Vet College or even an avian vet may be helpful. I did see that dark mass in the photos, but was just not quite sure what to make of it I also agree with you on the amount of fat in the abdomen. I still feel like it's a lot, especially for such a young girl. The way it was attached to the intestines, I have not seen that either. @Treerooted a few of the others are not online that frequently, so hopefully they will be by to take a look and give you their opinion. I wish we had better answers for you, thank you again for posting the photos. If you do happen to get someone to look at your photos, we would appreciate your sharing what you find out.
