I feel your pain
my box turtle won't eat much besides worms either, I am continuing to try the suggestions people have given. But she is a stubborn little bugger!
I only have experience with one 3 toed, It was found in Md. and was cared for like the easterns found locally and as far as I know it is doing fine still.
. I cut up some dandelion weed, kale, and red lettuce(which my little Eastern Box Turtle loves) into some really small chopped pieces, then put them in a ziploc bag. I then mix in a fruit, mushroom, or veggie of the day(of course all cut small and washed thoroughly). I cut up a red wiggler, night crawler, or meal/ silk worm(whatever the worm of the day is) and mix in the fruit/veggie mix. Mist it with water, then I take a whole worm, mist it with water and then I place the worm or worms in the ziploc bag and batter the greens on the worms(they stick pretty descent on the worm). Place the worms on the dish, then the fruit and veggie, worm mix, then the rest of the fine cuts in ziploc. Sprinkle some flukers calcium and vitamins, give it one last mist, and place it in the enclosure. I keep 1-3 gut fed small crickets in at anyone time. They usually try to eat off the dish, a nice trap for Chloe. I keep pill bugs, red wigglers and night crawlers in the enclosure also. I am raising brown garden snails to mix in a variety, she eats them like a champ. They are easy to raise, but you do need to file a permit with USDA if you were to move and take them from state to state.
