I have a female carolina bauri I ended up with because someone dropped it off at the pet store....After one year, it will tolerate me being within 5 feet ! (used to be 10.)
Box turtles are very shy animals. Compared to toetoises they can be considered boring cuz they just sit in there shell. I've had a lot if different box turtles and I have had friendly ones and shy ones. If its a shy one likely it's never going to be trusting, but doesn't mean it's boring they just are cautious. Right now I have two and one is out going likes his head scratched the other will sit there with just her head out watching till she feels I'm not a threat. If I move to fast tho she will think twice. I use to have 30 plus at one time and I found box turtles all have there own personalities and shyness or non shyness factor.
To me Box Turtles have the most personality. I have two Cherry Heads, and as sweet as they are, their personalities cannot compare with the boxies. Try feeding them at the same time each day, and eventually they will come out when they know the food is coming. I've had box turtles for over thirty years, and each one has a different personality. They make me laugh every time I go out in the garden. If I'm kneeling in the garden pulling out weeds, some will come running from whereever they are to see if I dug up a worm, and they will actually crawl on my hand. I have Three Toed's, Eastern's and a Gulf Coast who thinks he is the watch dog of the garden. He will run out from whereever he is hiding if he sees someone he doesn't know, and charges with his mouth open to scare them away. He does this when my Chihuahua's look into the garden too. I don't think I have ever gone out in the garden, that some didn't come running to me looking for a treat. I always have some fruit or a worm when I go out and they know it. Very comical. I could go on and on about each one's personality, and I have a thousand pictures too. Nothing like them!
