Can you breed a broken chestnut with a broken chinchilla rabbit?

Hi, I bred rabbits for 4h too. Honestly, what my experience was, is that if you are wanting to sell the rabbit's babies, you should breed in the same kind of rabbit and then the markings will be fine no matter what. My opinion is that the markings would be fine and fairly cute. Even sometimes you get a whole different color of rabbit from one of their parents' parents. The markings can sometimes be unpredictable, but I think you should just do what you want to do.
