I'm going to get another baby tortoise in two weeks so I built another 3x7 feet table. I started Kiwi in a 40 gallon breeder aquarium for the first year before I put him in my first 3x7 table. I'm assuming the baby to either be a hatchling or maybe at most 3 inches. Should I block off half the enclosure and slowly expand it once the baby gets a bit bigger or just let it roam the full 7 feet? Don't want the little guy to be too tuckered out trying to get to the heat or get to the cool side.
