Welcome and great birds. Not easy to get a silver columbian free of black markings on body like your roo.
Could you show a side shot of that chick? want to see color.
I've done naked necked polish, they looked awesome.. I thought they looked better than regular polish because the naked neck made for more contrast with the crest, made the crests look rounder and larger. For many years had many projects involving naked necks.... don't have most of them anymore. My current projects are lavender in bantams(Knock Kneed Hen has one, pics just a couple pages ago), laced, maybe pencilled too in standards and eventually large fowl, just plain trying to increase height and weight in my large fowl group(some of them lay colored eggs too).
