If you have one snake, it's not worth breeding them at all..

I would also not breed the American Blues, they tend to have immune system problems and the females have issues with birthing and hemorrhaging.

If the males are babies, wait a few more months. Females should be at least 5-6 months and over 250grams. Get her a buddy and wait. Or just breed mice. Or buy frozen...
