My juvenile bearded dragon has had this thick yellow clumps on his neck and face for months. I thought it was him shedding, but this stuff is like rubber. Plus he has a blister on his eye and lip. I have a clean cage and uvb/uva lighting (75 watt for uva & 13 watt uvb). We give him a bath with an aloe Vera soak for reptile shedding twice a week. He had calcium and multivitamins on his food. Likes to bask all day. He’s at least 11 inches away from light. Help!
