We have a 3 year old male bearded dragon. Recently his scales have turned orange on the 'lip' of his bottom jaw.
What is this?
He has a combined UVB / heat lamp. We dust his crickets about once a week with mixed calcium powder and multi-vitamin powder. Heat in the aquarium is correct according to the care sheets I have read. He is not very fond of vegetables at all so I feed vegetables to the crickets.
