I would wonder if the 400-500 gram breeding males who hook up, what percent actually knock the snake up?
I don't think it's so much of if the snake will hook up ... it's more important to know that it's very easy to kill a 400-500 gram male by breeding it. Male ball pythons will literally breed themselves to death if you let them, and the younger/weaker a male is, the easier it is to make that happen.
