Caramels are an awesome mutation. They live long healthy lives and breed like any other ball. I have yet to see a Female Caramel sitting on a viable clutch... however het females produce like crazy! People make all sorts of claims... incubation temps, rat diet etc but the truth is: We haven't quite nailed down the kinking thing!
Ralph Davis has some kinked males... check the breeding records... i think he got some of them to breed!
