I have seen this a couple of times, and even had it happen in one of my babies. My female had low calcium reserves because she'd just laid a clutch the month before, and I didn't realize she was gravid again so I didn't pump her full of calcuim quick enough. She laid a clutch of 1 large fertile egg and 1 small soft unfertile egg. The baby incubated fine and hatched on it's own but has a permanent underbite. I saw your ad on kingsnake, the one you're offering is a little more promenent of an underbite, but it's essentially the same as mine. She eats fine, and actually grew much faster than any of my other chahoua babies. It is not genetic, just a calcium reserve issue from incubation. I'm sure the results of this are similar to having an animal that had mild MBD but has recovered if given proper calcium after hatching and during young growth. When I eventually breed my female I'll let you know if there are any issues with the female's offspring or eggs. This is my girl (in the middle)
