So the egg with less boob ended up rotting out after a short time.

The other boob egg I let go full term as I saw veins. The mold was getting worse as time went on, but it was an interesting experiment.

In the end the other boob was filled with firm (read: solid) white/yellow stuff. Almost like a hard boiled egg. I couldn't identify anything remotely snakelike in there.

The other five babies are pipping and look good.
