How old/large should a female be for breeding. With ball pythons we have the 1500g "rule" and at least 2 years old. What is it with boas? I have a boa that had some feeding issues for a while so she is extremely small for her age. She is a 2008 normal. If I can get her to calm down for handling I would like to keep her and eventually breed her one day. So I'm just wondering what is the "rule" for females. What about males?
