Boa shedding query

[angelic]

Hello Newbie here!!

I'm taking on a Boa Constrictor Imperator, she's about 5 ft at the moment, and not very well. She's up for adoption because she was rescued from some idiot who didn't know what he was doing at all. She's in a terrible state, and I really don't know how its happened, which is what I'm hoping someone can help with.

She's got about 5 layers of unshed skin, which is really really dry and almost hanging off her. Her eyecaps obviously haven't shed for a long time, they are practically black, poor thing. I'm not taking her on until she's shed the skin, but I would really like to know how this could have happened in the first place, has anyone come across this kind of thing before?

Is she likely to have any recurrent health problems because of this?

Thanks

Angelic
