I personally would be concerned about making a ball python that has duck-billing AND a spin and/or wobble. I request that you let us know the out come of ALL of the eggs. I would LOVE to see what a super-cinny-spider looks like! I think that would be the reason that no one else has made it yet. It's a risky project, but I wish you ALL the luck in the world, and HOPE that you don't need to freeze any of them.
Good luck man, and PLEASE give us full details.
I don't know, but maybe incubating at 87 degrees, might give them a little more time to fully develop so to avoid possible duck-billing.
Man, why did you post this???? I can't WAIT to see one now!
