Do they shed or slough skin normally or is Turtle being a naughty boy? The skin on his neck is a bit flakey and dry and I'm not sure if that is OK or not. He drinks a lot, pees a lot, eats a lot and poops a lot and is pretty active so I'm not too worried about any of that, but the flaking is puzzling. I tried to get a picture but he won't cooperate and leave his little head out long enough. It's only just started, hasn't been there for long and is minor...just wanted to check on it though. Any ideas or am I just worrying for no reason?
