Some of them never calm down; my male LaVey would be a great example of that I still love him like the awesome little gem he is, but he is def. a pi$ser in the attitude department. Sounds like yours has had so much stress; I would probably hold off on any unnecessary handling and just take him at face value for now; you could always get a second one that has a better demeanor to "handle" and let him go at his own pace.
