I would image coming from a bigger breeder is the issue they probably never handled her a lot at all seeing that she was not a pet and just a breeder.. that may be something you need to remember... Dont handle her like you would your other 3 bps because they are pets... its not enjoyable for her she probably would rather be in her rack in the dark not being bothered..JMO maybe she will not be a pet for you just a breeder..I have a female normal that is the same way and we both have learned to respect each other...I dont hold her more than necessary and she doesnt bite me more than necessary LOL...
