Hi, I keep 3 red foot tortoises 1 yearling & 2 juveniles. I've only been keeping tortoises for under 2 years & like to know how to tell if my red foots are fat from over eating, I feed them a large variety & assortments of feeds other than Mazuri tortoise diets & they get several hours weekly to roam at outdoor grass fields & sunlight, with the amounts of exercise & vitamin D exposures are the chances less lightly?
