Vitamin/mineral deficiencies are possibilities, as well as the other suggestions. Breeder females of most species need greater amounts than non-breeders. Deficiencies are known to cause infertility, still births, and birth defects.

All of this is true for trout, humans, and chickens, to name only three. In my opinion, it is likely to be true for snakes, too. I think that we still have a lot to learn about reptile nutrition.

Here's a reference you might like to dip into:
