When you say lots of skin attached, do you mean stuck shead? if so there are a number of things you can try. Shed Ease, a lukewarm bath and crawl through a pillow case, gently rubbing it off, etc. I would use caution around the injured area, though, and try not to get it wet with Shed Ease. It may irritate bare skin. For the eating issue, was he checked for parasites? If that comes up clean then you may need to wait for his appetite to naturally return. A ose of Jump Start or force feeding may be necessary if he starts losing a lot of weight.
You mentioned owning other snakes so I assume your enclosure setup has good hot/cold sides and humidity. Good on you for taking in an unwanted BP!![]()
