i found a clutch a turtle eggs a couple years ago that a raccoon had ravaged. there were 4 or 5 good eggs so i took them home and threw them into the incubator with my cornsnake eggs. i used the same medium as they were found in an just placed them in the incubator. they all hatched perfectly ...btw they ended up being eastern soft shelled turtles and i released them back to were they were laid a week afetr hatching.
