I've got a 12 year old female albino that I produced myself that has never laid an egg. Though she pops and probes as a female I've even put her in with other females for the season just to see if I'm wrong on the sex, still never saw any breeding and nary an egg. This past year she's been the constant roommate for my retired het albino male, I don't use him for breeding anymore anyway so I'm just going to leave those two together year round. If anything happens then great, but I really don't have any expectations. She's just a really nice pet snake.
