The blue tint may be the lighting.

Wish I had a video camera I could dedicate to filming a hatching. That would be cool.

Last year I had the pleasure of watching an egg burst open - with a slit rapidly forming.

This year w/ my kingsnake eggs - I checked on them, moved my head away to drink my coffee - looked back and a slit had been made in the that time.
