I presume the discharge you're talking about is clear? As long as it doesn't become thick (nor change color) or interfere with normal activity...I would avoid the Vet at all costs. They wind up doing more harm than good! If the weather gets too cold, try keeping them in a large closed chamber. If you can maintain heat at 85º or more...and keep humidity high...at least 75% there's nothing a Vet could do that would be better than that!I don't think you can take them to a vet in TN. They are illegal to own along with any other turtle/tortoise.
