I was looking at some pics of chickens and the thought suddnely occured to me. Beside's mixing a frizzled bird with an non-frizzled bird, how to do you get a 100% frizzled chicken? For example, I love Polish fowl. I saw some pictures of frizzled Polish chickens and thought how this could be. Obviously, someone mixed a frizzled bird with a Polish and the outcome was so, but how did the Polish gene become so strong, the crest became larger? Over the years of breeding them, how did it become it's own breed? Anyone understand what I'm getting at here?
