It's amazing how resilient their eggs can be. Sometimes they don't bury their eggs but evidently just deposit them in a recess somewhere. I happened to find one of these eggs and resolved to take it home and perhaps incubate the egg. I placed it in my shirt pocket, spent the rest of the day in the woods, and when I got home I sat the egg in a dish on my utility room shelf. Well although I was well intentioned the egg sat there for a couple of months until one of my tortoises laid. As I had to set up my tortoise eggs I also put the little mud turtle egg in with them and low and behold, about six weeks later I had a perfect little striped mud turtle. Amazing that the egg could take so much abuse and still hatch?!
