Is there any way to find the age of a turtle? Had her for 5 months now.Adopted her as a stray. Had the Vet sex her, but not date. Getting a new custom terrarium in a week.
Not likely. Turtles/Tortoises growth is closely related to food supply. More food, means quicker growth. Sorry, but there really isn't a way to give you a good age. You can estimate, 2-5 years old as an example, but even that isn't reliable.
Sorry!

Check its driver's license! Emotion: smile
Seriously though, there isn't a reliable means of determining age. Growth rings on the shell and size can be wildly different for turtles of the same age depending on how well the turtle has lived since it hatched (feeding, temps, etc).
What kind of turtle is it? "Western" box turtle leads me to believe it's Terrapene ornata . Where do you live? Keep it outside for as long out of the year as possible. I've had my ornata for over 20 years now.

yes I do believe she is a Terrapene Ornata. She gets regular walks outside for exercise and natural sunlight. I live in Southern California so I don't know what I'm going to do about hibernation. the best I can do is somekind of container in the garage. But I don't want her to just zone out and lose weight.

I've found that for certain species growth rings can be fairly accurate. Case in point: I spent the summer working on a Bog turtle mark/recapture study that has been ongoing for approx. 10 years. We found that turtles that that had been marked at the beginning of the study had the appropriate amount of additional annual growth rings when they were captured this year. Of course, we often had to count rings on multiple scutes to acheive an "average" number of growth rings for an individual animal, but scutes were never off by more than 1 or 2 for an individual. Also, this method doesn't work on older animals because the shell is often too worn to see the rings.
If nothing else, counting rings should give you a ball-park estimate if not an exact age. Remember when you count to exclude the innermost ring, as that one was present at hatching, and to count rings on several scutes on the carapace and plastron.

"Zoning out" is basically what it's all about. I weigh my box turtles weekly while they're dormant, and you'd be surprised at how little weight they lose, even over a period of months in only the 50s.
