I have a rescued red Foot which I am guessing to be around 10 years old and about 9 lbs. He had a injury to his back leg which is healing but now the skin/scales on his front legs is peeling off. He is still active and eating and doesn't seem to be sick. This has been going on for aobut a month. Any ideas what is coausing his sking to slowly peel off?
