As I've been saying, like has nothing to do with it. Dietary requirements do. A few wise keepers and breeders have made omelette treats with chopped up veggies in them, add some red bell peppers for a bright attractive color and I doubt any turtle could resist. I chop all my veggies finely and mix fruit in - cut small as well. It makes it harder for them to pick it out.I'm sure they hate my scheming ways to make them eat well!
If you decide to release them, they need to go back to the area you found them. Turtles have home ranges (actually most animals do), when relocated out of it they face starvation, dehydration, and predation as they won't know safe places to hide/nest. They managed that area for the last 6-30 years (maybe more) just fine.
I hope they come out of hibernation safe and sound. Make sure to give them a nice soak so they can rehydrate after the long winter.
Wild mud turtles are icky. Wild muds, musks, and snappers always smell like something rotten. That beauty in the picture I linked to sure had an odor.
Vixen, have you been able to find all the proper lights, fixtures, and thermometers you need? If you have problems getting supplies and supplements at your local pet stores, or just want to save a little money, you can try this online store http://www.reptilesupply.com/
I have bought bulbs and other items from them a few times, no problems at all and had very quick processing + shipping. Some people have complained about their orders being slower to process, though.
...Check your state laws before messing with any wild life. Texas now has a law that if you so much as get out of your car to move a turtle they can fine you with hunting on public land.
In Arlyn's case, species like gila monsters and tortoises have strict protection in some states. You can actually get in trouble for "molesting" them just by being close enough to photograph - without proper permits. I'll look forward to those pictures, but please don't get yourself in trouble!
I did bookmark your sites that you posted for Box turtles. I will have lots of questions for you!!
I'm glad I popped into this discussion.
