I seem to recall it is something seen with early pippers where the snake hasn't quite finished developing. Iirc the head fills out when the baby eats and grows.
I hope that is the case. The poor guy crawled out of the egg today and weighs 70g. I'm hoping I can get him into the vet school to X-ray his head and see what is going on. He otherwise seems healthy.
