when you pick up a adult "20 pluse pounds" tortoise, does it hurt them. I have an adult tortoise he wheighs around 40lbs. When I lift him i scoop my fingers under the bottom of his shell "the part that is sitting on the ground" I am would really like to know if this hurts him because he pokes his head and legs out very far. I just want to make sure that I am not causing him pain or pressure. Thank you...
