neurological problems...what are your thoughts??

Those are some pretty babies. However, I am a little confused on that situation too. But I really like the way they look. I would want one even with their problems. I love yellow snake they would make pretty pet.
 
I have never heard of any genetic, corn snake, "star gazer" type defect, except the one that arose from the sunkissed line. Of course, it has been around long enough that it has been bred into many unrelated lines. I am sure somebody has probably bred it into some creamsicles by now. But I have never personally seen or heard of a creamsicle that exhibited it. I would be interested to read the studies myself. Maybe a particular client or two has a line descended from sunkissed animals, and that is why a particular vet is seeing it? I don't think it is in creamsicle lines generally, or it would have reported more widely. Or it is something entirely new that this vet has discovered? Can't think of any other explanations, but would be interested to hear about it.

Also, since I have never heard of any other genetic star gazing corns (besides sunkissed lines), inbreeding probably doesn't have anything to do with it, UNLESS it has descended from sunkissed, and was inbred sufficiently to bring out the trait (just like any other recessive morph trait was produced).

I watched the video and it does not appear to me to be the same trait as the sunkissed I have seen. They usually show much more evidence of neck twisting, dipping, and moving upside down. Of course, I suppose some could manifest in a different way than I have seen. But the several dozen or more that I have observed all moved in very similar ways, and didn't look the same as the video.

My guess (and it is only a guess, based on past observations) is that it is probably not genetic, but incubation related, caused by either temp or moisture problems, or some environmental toxin present at the "wrong" time during development.

If you breed the same pair again, try to incubate them in the same time, place, and conditions as another couple of clutches. If you get the same defect with this pair, but not the others that are incubated with them, then that would show evidence of a genetic defect. And it might be a new one, although you would have to breed it to the sunkissed 'gazers to find out. Since it is not a desirable trait, you probably wouldn't want to go through all of that work to find the answer, unless you are just really curious.
 
I now have 3 hatchlings total, with one unpipped egg, from this pair that exhibit this same behavior. The new baby does have SOME degree of the same movement, but not to the same extent as the other 2. I actually think the older 2 babies are getting worse/less stable with movement, but this could also be due to being 6-7 weeks out and not having eaten. The first clutch was incubated under the same conditions as another clutch which turned out completely normal...room temp (79-84 degrees, damp spaghnum moss, on a shelf in identical tupperware containers). These eggs took 2-3 days longer incubation than the normal clutch, but hatched around day 67, and actually both clutches hatched within a couple days of each other. So I seriously doubt there's anything environment/incubation related. It's certainly possible it could be caused by a disease, but none of my other snakes (parents included) show ANY symptoms of this. I do think it must be some sort of genetic/developmental issue. The parents were from unrelated breeders and are not known to have any sunkissed parentage, but who ever knows?

Kathy, I'd like to take another video of the babies and have you watch it and see if you still don't believe it's manifested the same as the stargazing you've seen. Do SK SG have any other abnormalities other than gazing? These babies definitely have very small heads, with weird head patterns (each just has a splotch of stripe color on its head, no actual markings), and the first two have mild kinks.

I actually don't have any plans to breed the cream stripe mom next year, and definitely will not be repeating this breeding! I suspect she's the source of the problems.
 
4th messed up baby born...this one is identical to his clutch mate (butter stripe? weird) but also has an everted hemipene. Hm. Waiting for a first shed on these guys; they're in blue so shouldn't be long.
