How can you tell the age of a russian tortoise?I have a young female and a friend of mine found an older male russian in the road and knew I already had one so she asked if id care for him. I said yes and set him up a separate area of his own indoors. He's very thin and I'm praying I can nurse him back to health! I was wondering if there is a way to tell their age? I know he's older than my female but I wonder by home much?? Id apperciate your answers. Thank you.
