I have a large group of these given to me two years ago. They live outside and have a little pond and heated night box. They are mainly eating the same diet as my box turtles. I have yet to see any breeding or nest digging. I'm wondering if they are secretive about breeding or nest digging. At what time of day do they dig nests (in the evenings like box turtles?) Any advice from someone who has experience with these lovely turtles would be much appreciated!
