My bearded dragon is around 11 or 12 months old, and he has not shed in months. Over the last 2 weeks a random large patch on his back has been getting darker and darker and he is finally starting to peel up on the edges. Every other time he has shed it has been neat defined sections, this is the first time that a random large patch has shed like this, im assuming its normal but i just want to be 100% sure. it goes from his right shoulder to the left side of the base of his tail for a general idea of the shape.
