There seems to be lots of questions/photos about color varieties and I'd like to add a few general bits of info. While everyone needs to think/see type, may folks are equally (or maybe more) interested in colors. The subject of genetics may seem difficult, becuase of the number of genes that can be involved depending on the pattern, but there are some great resources out here (Internet) to help understand.
One resource I'm been smitten with (although its expensive) is "Genetics of Chicken Colours" by Van Dort, Hancock, and freinds. Its a book out of Europe where the knowledge on chicken genetics is much wider known that here in the US. The best part of the book is the "recipe" section in the back of the book. There are pictures of nearly every possible color and the genes needed to make that color (regardless of breed). It is very helpful if you want to try creating a particular color. For those who can't justify the large cost of the book (around $140 US from the Sernam Club I think), you might try to get your local library to purchase it. They are always looking for suggestions from their readers for purchases and that might get you access to a copy.
A free resouce - although the knowledge base is kind of high - is the website forums on "The Coop" (
www.the-coop.org ) . It is out of Europe and has also been helpful once you have a basic understanding of basic genetics. There are discussions of many "breeding projects" that are worth the reading alone.
Lastly, the ABA Standard has descriptions of recongized colors also near the end. There it lists what colors should be where on all of the colors that are recognized as standard colors. Nonstandard colors are sort of anything goes until accepted into the standard
OR you have a target in mind. For example, I'm starting a Mille Fleur cochin project (nonstandard color for cochins). What I'm working toward would be a Mille Fleur pattern (which is a standard color), so I can look that up in the Standard to see what to cull for in terms of color. Again, if you find it difficult to justify the cost of the standard, suggest that to the library too.
