Diamonds are spring breeders, Ovulation looks like they have eaten a big feed, you can't really miss it if your looking daily, for carpets at least. Basically you put your snakes together....they mate on and off for weeks / months, female gets fat towards her lower end.... people think Oh my snakes gravid... it's just unfertilized egg follicles forming.... if ovulation doesn't take place for some reason she will just reabsorb all the follicles and leave the keeper scratching their heads.... if she ovulates she will have eggs.
