I bought a horsfield tortoise for my daughter he is 14 months old, the breeder we bought him from told me he just needed a small layer of aspine in the box but having read about them it says they like to dig and burrow,they told me to feed him on lettuce (not iceburg) and grass and weeds,Ive only had him 3 days and he has runny poo he has very runny poo is this normal.Everywhere seems to have conflicting care sheets I really want to provide the right enviroment for george can you help .Thank you
