I've never had the heart to ask, but I'm pretty sure her eggs were not allowed to develop. That would have been a responsible thing to do on the part of the rescue.
I was told Mandy was supposed to 12-ish when she came to the rescue. I just used that number because when I got her I didn't know she had been there for so long. I designated June 14 for her birthday and call her 13 now. No one knows for sure.
Here's a copy of her ad on PetFinder. Obviously she was in shed in the picture. I did ask when I picked her up from the rescue, if she laid every year. They said she arrived at the rescue with male and had not laid again.
One thing they got wrong in the ad is that she handles beautifully. As you can tell, I gave her a more feminine name that seems to fit her personality better. I'm sure that with time and good care she learned to trust and be handled. I wanted her because she needed a quiet home with time to devote to her. I could also give her a spacious enclosure all to herself. They were thrilled when I asked to adopt her and I was thrilled when they said yes!
