ASF temperaments seem to vary a lot. One of my colonies is so mean that the females jump at my hand trying to bite. They will attack any new comer. But my other 2 colonies are very laid back. They let me touch them or pet them and they don't care. It really depends.

As for the new babies, I've noticed ASFs are pregnant longer than other rodents since the babies are so small and grow so long. I would think its possible that female was already pregnant. It may also be possible that sperm was retained but I didn't think mammals could do this. Does anyone know how the gestation of ASFs? Or how long after mating can sperm live before the female ovulates?
