baby box turtle sexing

At what age can box turtles be sexed. I have a three year old. Are there any tell tell signs. And i'm seeking box turtle room mates. I know adult sexing methods . Thanks Darren

It is easier to tell the difference of males and females when you have two turtles together. Females have a taller, rounder shell, males are generally flat compared to a female. Females have a flat plasteron and males have a concaved plasteron. The shape of their tails and even their hind legs can help you know the difference. Even the red iris of the eyes that males have females do not have.

Here are pics of my male and females, you can get an idea of the shell shape and eyes from these pics. I do need to get better shots of them though.

Adult Femle:


Young Female:
