One really strange thing I've noticed is that my mostly blonde village has had 170 babies made so far, but no triplets have born yet. Perhaps the blondes are less fertile?

In one dark-haired village, I've had 306 babies and 4 sets of triplets, in another dark-haired village I've had 551 babies and 12 sets of triplets, and in a dark hair/red hair village I've had 657 babies and 11 sets of triplets.
