CONGRATULATIONS!!! There's nothing like your first hatchlings, and hearing that alien scream always amazes me that something so small can have that much lung power!
The white and black banded one could very well be just a premie and not a mack snow, looks on the small size.
It has been a long time now and both of them are eating. The little one still has that white and black stripes. But she is a little slow on eating. But she eats about 8 crickets a day.
