Researching this before you picked up your animals would probably be your best bet. You can't guarantee no kinks in the offspring... If people could do that then we wouldn't have so many people freaking out about kinked caramels.

I've heard of a few things that could possibly help, either incubating slightly cooler, slightly dryer perhaps, but i don't keep caramels and the only person i did know who did is no longer in the hobby so i can't ask them.

There are threads and threads on this though i'm fairly sure.
