Runner Ducks have their own version of table top. They are judged moving around in a pen, at the show's discretion, and although I have no idea what they're looking for, it's pretty fun to watch. Ducks make me giggle...
And as far as color breeding goes, I believe that I read something a while back about color categories in Malaysia. There were three categories, and there was an order of preference for each. I remember that the 'best' color was one that was red or buff based, but the others escape me. Granted, colors had very little to do with results, but it bears to mention that even the Malaysians aren't completely 'color blind.' I can't find my source, as it has likely been deleted from the forum where I read it. Something to chew on, I guess.
