Brought home a severely underweight BP baby. Please help me get her back on track

[Bogertophis]

.... just noticed this photo though .. what on earth caused that apparent split in the skin !!?? ....

Chronic malnutrition in snakes results in skin that tears very easily...I've taken in a similar snake (a boa) myself with the same problem. In case you want to
hear this from more than just one member? It's horribly challenging to treat & yeah, the pictures are shocking, to say the least...but this snake is recovering.
