I posted a question earlier about leaving my (almost) yearlings outside all the time. I have left them out all day today and plan to leave them overnight. My concern is this: Three times I have found one of them outside during the day on his back and he couldn't get turned back over. I know too much protein will cause their shells to grow faster than their bodies, but they really have had a variety of foods all winter. Is this a concern? Will they eventually get turned back over if I leave them alone?
