My neighbor asked if I'd be interested in taking in some turtles from someone. After some questions it sounds they like are 3 toed box turtles. The tank they are in looks small and apparently they are fed calcium dusted lettuce once a week which doesn't sound ideal either. Outdoor enclosures seem recommended but idk that northern MN is suitable for that very long. Should they be brumated? I'm seeing way varied advice on temps, feeding, housing for these guys and not sure what I might be considering. They are 10-15+ years old, passed around every 5 years it sounds like.
