Bob has been pacing all day so I went to get him out. When I did his beard was already completely blackened. I put him in the shower in hopes that is would calm him down, but it didn't. So I took him outside to get some sunlight and he didn't seem to like that either. He puffed all up at me. I put him back in his cage and he's pacing again. He's really dark in color too. Should I be worried?
