Vinke, T. & Vinke, S. 2004. Maintaining and keeping the Ornate Box Turtle, Terrapene ornata ornata. 1997. Geographic Distribution. Terrapene ornata ornata. It’s not uncommon among turtle keepers to dust the food with calcium before serving it. They ought to be provided a calcium supplement to maintain their cubes healthily and powerful. They have dark black or brown bodies and big, sloping shells which are curved towards the trunk. They have a powerful instinct for grinding so that they may earn a humid microenvironment for them, so give them heavy, excellent soil to dig and stumps or planks to hide beneath. In outside enclosures, both thick prairie blossoms and low-lying shrubs provide shelter and shade to conceal. Do not place the enclosure below a big shade tree or within a place that floods after storms.
