I do not recommend breeding a female that young. There can be too many difficulties that may arise. Why not wait another year and allow her to get to grow to a bigger size so she can handle the strain of the eggs. And there is the possibility that she can die after laying her eggs because of her small size. Females will refuse to eat while with eggs and they take most of her nutrients for the development of the eggs, leaving her very thin and weak after laying.
So, if you want to your female, why not wait another year allowing her to get bigger and while you're waiting read upn on breeding as much as you can.
I'm crazy for Burms!!
