Yes, it's a myth. Someone asked for pictures of a caramel sitting on her eggs, and since nobody really had thought to take pics of every snake clutch in their collection the myth was formed that they dont lay eggs and you only want hets. The reality is most people breeding higher end stuff like caramels have seen enough clutches that, while its always cool, they dont feel the need to take pictures of it allI'm sure now that the rumor has gotten out we will probably see some caramel girls on eggs documented soon.
