I'll second what Lawrence said. Don't let it get you down. I had an animal, not 2 headed, last year that was similar to that snake. Went full term, and even came half way out of the egg last year. After it died before fully emerging, my wife cut the egg and pulled out a fused belly and severly kinked tail portion, animal. It is sad, but it does happen. We can only hope to see something once in our lifetime with our collections. I hope you never have to experience that again.
Sincerely,
