Hello everyone! Just joined the forum. I've always wanted a BP, and have helped take care of a few while volunteering at the zoo and for my own school's education program, and I just got one, though rather unexpectedly.

Peaches, as she is now named, formerly belonged to a senior who is graduating in a week and cannot take the snake with her. She was desperate to find someone she knew was responsible and didn't want to post on craigslist, so I stepped in and offered to take her.

History: It's estimated that she's ~3 years old. Her first owner was an idiot had her for a year and told the senior when she bought the snake that...I sincerely hope you're sitting down for this...snakes absorbed water through their scales and didn't need to be given water. WTF! It's a miracle she survived him.
The senior had Peaches for about a year and a half and did an okay job rehabbing her. She says that Peaches was tiny as a yearling, and has grown a lot. Thankfully she was given water, lol, fed regularly, and handles very well. I don't think her tank was ever misted, as the senior said Peaches has never experienced a clean shed.

She came with a 20 gallon tank, a giant igloo meant for rats or a small rabbit, a log BARELY usable as a hide, and a ceramic plate/bowl thing for a water dish. YIKES.

I went out and bought her a proper soaking bowl, two cave hides, and little bit of decor structured for climbing. I'm buying a nice exoterra tomorrow and will be modifying it for when she grows.

SO. I've got a poor little girl who is probably 1.5 feet max (I'm measuring and weighing her tomorrow), and according to my zoo's Asst. Education Director, is half the size she should be (she's not starving, but I think she is on the skinny size). She's got a gigantic patch of old shed stuck to her head and running 5 inches down her neck.
Now, I'm used to taking care of nice, healthy BPs. I'm not really sure how to rehab a scraggly one. Peaches is just big enough to take adult mice. Should I give her two per feeding to help her put on some weight and try and help her get to a more normal size? What do I do about this old shed? I know I'm supposed to soak her, but how do I go about doing that? How hot should that water be?

Any advice would be helpful. She's got such a sweet temperament despite all these stressful situations she's had (hence her name) and I would hate for that to change.
