From posts I've read it sounds like about half of the imported caramels where kinked and that the normals in caramel clutches don't appear to have any increased incidence of kinking. It's really looking to me like the tendency to kink is just part of the caramel mutation and not a separate gene that could have been bred out by now.

That said, genetically I don't see how not breeding caramel X caramel could help. Say you produce a clutch of caramels and hets. Other than the caramel gene, how would keeping two of the caramels back for breeders be different than keeping two of the hets back? They are all the same amount of inbreeding. Of course we should still gather the stats and if it really does produce a higher percentage of kinks from caramel X caramel then come up with some theory as to why. Maybe female caramels are more likely to produce eggs that encourage kinking than het females.

If some breeders are producing large numbers of caramels with now or a low percentage of kinking then we need to figure out what they are doing differently. I think incubation techniques or perhaps nutrition might be the best bet for a workaround to this kinking tendency that to me seems to be just a part of the mutation.
