I got this adorable BB Red for Christmas. He has been doing fine. However the past few days, I noticed that it looked like something ws on his face. At first I thought it was dirt or mud since we have had some periods of heavy rain. But it didn't go away. I brought him inside tonight to check him out and this is what it looks like. The spots are hard almost like someone would have warts. This other side of his face looks perfect. What could be wrong and what do I need to do?
