Definitely female as it does not have any spurs on the backs of her feet. Age is hard to tell as they grow at different rates. She is going to need a lay bin in her cage at all times, it is very important for females, if they don't have one they will get egg bound and die. Females lay even without a male.

the pet store owner said it was male. Guess he lied :/ (Remind me not to go back to him.) Also, can do you think I could use a Dragon strand nest box with an X Large Reptibreeze for when she lays?
