for the last week or so, my ball python has had a dry, tan, almost crusty looking face. it almost looks like dry dirt, but doesn't come off. i've been thinking he's going to shed, but hasn't yet. i've had him a little over a month. i've never heard him make any sounds or do anything that would make me think it was a RI. he eats fine. he has a warm side of around 92, cool side around 82-85. humidity ranges 50-mid 50s.

anybody seen something like this before?
