Silver and gold sebrights are the most common. The other colors are around but it is very hard to find good quality as they are still being developed. Even the silvers and gold have been ruined by uninterested breeders. I have seen so many auctions on e-bay and eggbid that show just horrible versions of the breeds. It amazes me that people will proudly display a picture of a rooster with hackles, saddles and even a huge sickle tail and then call them sebrights.
In my opinion, if you are selling a breed then you should at least know if your birds are anywhere close to the standard. If not, sell them as barnyard mixes.
