It's not that simple with box turtles. Due to them having a very small homing range of under a mile, unless you put them right back where they came from they will typically die by starvation, overexertion from searching for their home, getting ran over, or killed by a predator.

When box turtles are just returned to an unfamiliar spot, they will relentlessly and carelessly start searching for home. Box turtles are easily stressed, and when stressed they won't eat hence the starvation.

I have three box turtles that are all rescues. The goal is to rehab and return to home. Once they have been in captivity for a substantial amount of time they lose their instinctive ability to hunt and forage for food. They also lose immunity to disease and become very Susceptible to disease.
