On second thought, breed under close supervision if possible. The male snake may be put off by her odd behavior and be more opt to get aggressive, or maybe take the wrecked honker as a sign of weakness and be more opt to get agressive. Those were the only drawbacks I could really see to putting her with another snake.
Would you date someone who banged thier head against a window for odd reasons even though it caused them to injure them selves?
