I dont think you're going to get anyone to say yes thats a het. This is more of a comparison thread. Like even if you bred het to het you couldnt sell the normal babies as 100% hets since it all boils down to percentages and recessive genes. Even if you are positive as the breeder that those normals look exactly like every other het you have proved out.
BUT, that snake you have pictured does look alot like my het caramels. What do the eyes look like? Mine have lighter eyes than a normal. A bronze tint to the top color of the eye.
I believe there are quite alot of hets out there that no one even knows about but what are the chances of breeding 2 "normals" that look identical and getting something else?
Im having this dinker issue with my biggest normal female. She was bred to a pastel last year but the only baby that looked different (out of all pastels) was a female. Kind of a bummer that I cant breed back but I'll keep trying to figure it out.
