I have been told that the gene for the crest in Polish chickens is dominate. I take this to mean that no matter what you cross with a Polish chicken, it will have a crest.
Is this true. If not please explain.
i believe everything i have crossed with a polish as a crest. but not all get the vaulted skull. so some of my crosses have little poofs and some have larger crest, but usually not as big as the original polish
