Hello! I have had a male Russian tortoise named Peggy for the last 16 years. Today when going down to soak him i noticed part of his face was missing near his beak. Should I make an appointment with the vet for him. He has shed his beak before but this is not part of his beck. The bedding in his enclosure is cypress mulch and he eats a diet primarily consisting consisting of romaine lettuce, carrots, and occasional fruits. Thanks in advance.
