I received a new ball python a week or so ago with old bits of skin stuck to it.

My snakes shed fine, in the past if not I address it immediately. But this seems to be months old and seems welded on.

I have raised the humidity to 85% and tried a sweat box. I am concerned about raising the humidity for too long. its been 3 days at high humidity so far.

Any suggestions? Also how long can I leave it at high humidity? or can I wait till the next shed (worried that could cause skin damage)?

I don't think it will shed soon It arrived at less weight than the 4 month old advertisement and is no bigger than the picture of it then. (picture was in the persons hand for size comparison)
