I love turtles but I don't know a lot about them. I have two RES. I've figured out that one is a girl and the other is a boy. I can't figure out how old they are. The males shell is 4inches vertically and horizontally. The female's is 4 1/2 in. vertically but only 4 in. horizontally. How can I tell their age?
P.S. Not sure if it has anything to do with Spring finally arriving but my male has been extra frisky lately and his *you know what* made it's first appearance yesterday. Didn't know what it was at first, I thought he was hurt. I figured it out when it went back inside his tail. Is there a certain age when this happens?
