Pssst...Got Corn??
Really, your snakes skin shouldn't look like it's hanging off her, even after an extended period without a drink. I really think something else is wrong with the snake other than dehydration. If that's what is happening to your snake, I'd recommend a visit to a reputable reptile vet for a proper diagnosis before this condition worsens rather than make the assumption that it's because it is "developmentally disordered" as you put it.
