Well for one, looking at the pics. Thats not a bad shed, You can tell by looking at it.

Bad sheds are where the skin does not come off. A "bad shed" does not look like rotting scales. I mean just looking at it before you bought it and seeing the skin/scales are rotting off should of turned you away. Iv bought snakes before that had a bad shed, but thats just simply a stuck shed, not rotting scales.
