I did not create this colour; I traded with a friend: she got a pair of splash silkies and I got a pair of wc chocolate polish. I believe she purchased her breeder birds from one of the big name breeders who is working on (or may have initially bred the colour). These are I^D birds, not choc. I don;t have photos of mine, and it's too dark to get ones that will adequately show the colour, but here is a link to photos on the Polish Breeders Website http://www.polishbreedersclub.com/wcchocolatepolish.htm
I recieved this PM from Sonoran Silkies. He has a pair, so Im guessing he may sell chicks or eggs ???
I actually would be more interested in doing Chocolate Cochins.
I don't especially like Orpingtons. I wonder which people would like more?
Also if I do cochins, I could do mottled, which would be your chocolate with white spots, and after studying up on the matter, I have a bird that may be able to have chocolate offspring.
