600 Breeds, 3 Rainbow Skills

I breed 400 Chikipi's and 200 Jormuntides.

I got 0 rainbow skills on the Chikipi's and 3 rainbow skills (Remarkable Craftsmanship, Vampirism, and Demon God) on the Jormuntides.

Has anyone else been able to get Rainbow skills on Chikipi's?

I am interested in what others' results are.

(As an aside, as to why I made so many freaking chickens, I really needed a ton of eggs, they were limiting my cake production and now I am pounding out the cakes).

Edit: Update, while breeding Vampirism into my Knocklem, I got Diamond Body.

So far, I have been unable to breed a Rainbow skill from a parent that didn't already have it. I don't know if there might be a relationship there or not.
