Wow! Thanks so much! I really didn't expect to get so much information from this thread, but you have most definitely helped tons.
More than welcome. Due to improperly colored foundation stock, innocently purchased, I had Golden Duckwing invade a breeding program where I was trying to breed Black Breasted Red Marans ( BB Red) . Sigh. Then I unknowingly added in autosomal red and ended up with Red Shouldered Silver Duckwings. What a mess, the autosomal red polluted everything. It is very difficult to find in the chick down and juvenile feathering. Unless you become a serous student of proper chick down. I was so surprised at how just the slightest different in a tint in chick down in these color could manifest such differences in the adult coloring. Autosomal red is a real "sticky" color factor. Tough to get rid of once it invades a breeding program. I still see a notable number of people on the Net touting the lovely pics of their Silver Duckwings when it is obvious from the darker red patch on the shoulder that they really have Red Shouldered Silver Duckwings and are polluted with autosomal red.
Here, read this page of posts.

It's an in-depth discussion of my problems in that Marans breeding program. With genetic formulas and URL's to pics of the colors. We were discussing the Red Shouldered Silver Duckwing rooster in post # 12 which was thought to be a Golden Duckwing.
The only way to keep autosomal red out is to use
absolutely pure Golden Duckwing and Silver duckwing. Come to think of it, Ann Charles I think has both colors in her superb Araucana breeding program. She owns the great ezine
http://www.exhibitionpoultry.net/ Her website is
www.Skyblueegg.com That would be a neat breed to use. You would get the colors and cool colored eggs too. Ann has lovely show quality birds too. So you would get breed type, colored eggs and proper colors. I know the website is 2015. Give Ann a call and see what she has this year.
A Gold Duckwing is a Gold based bird. A Golden Duckwing is Silver based bird. Sigh, what confusion, smile.
This is why being able to converse in the genetic formulas is so valuable when breeding these colors. There are a number of "hobby" names for these different Duckwing colors. The color experts give advice by genetic formula. It is the best way to understand exactly which color one is discussing. The BYC poster, Marvin ( BYC nick is : nicalandia) is a human genetic calculator. VBG. Real nice guy.
Excellent in giving color genetics advice. Here is his BYC profile, shoot him some questions.
