Aside from the husbandry issues which are one of the major factor when it comes to stress you might also want to address feeding.
Fuzzies and I assume mice fuzzies (correct?) are way to small for a BP most hatchling are started on hoppers and quickly move to adult mice.
The reason I am addressing that point is that underfeeding your snake is an other factor that can explain his behavior in addition to the rest.
Here is some good reading and a good place to start working on your issue.
