Wow, what an interesting subject, what a beautiful turtle -- and what a challenge!!
I've just spent close to 2 hours on the internet looking for moving information relative to the Box Turtle. Found out they can live over 100 years! Found out lots about how intelligent they are, their living conditions, including temperature, humidity, food, hibernation....
Okay. I've got three suggestions:
1. Ask your turtle's doctor, your exotic pet veterinarian. The doctor has to know or will be able to find out pretty quickly.
2. Slog through the many, many Box Turtle care books in your local library.....
3. Contact this animal clinic, All Creatures Veterinary Clinic in Omaha.
All Creatures Veterinary-Home
They clearly know these animals -- this page of their website is all about the Box Turtle, although not about moving one:
All Creatures Veterinary-Box Turtle Care
I had to do some sleuthing to find out
where that clinic is. Here's the info, with area code for that phone number on their website:
MyVetOnline.com
A surprising possibility:
I clicked on "Activities" on this site, the Tortoise Trust Web page, "Avoiding Problems With Box Turtles":
Tortoise Trust Web - Avoiding problems with Box Turtles
and got this site, the Tortoise Trust Foundation:
Home
with this email address:
tortoisetrust@aol.com
You could send them an email, imploring them to please help you....
I hope this helps! And I wish you all well.
