Never had a Ball do this, but I had a 6-7 ft female Dumerils Boa that I had problems getting to breed. I probed her and had her confirmed as a female by another breeder, but she would attack any male put into her enclosure. If I put her into the male's enclosure she was fine. I think she was the most territorial snake I've ever seen.

I've had to pick teeth out of the male snake twice before I figured out what her problem was.
