Chicken colors; genetics

Date sort Score sort
Some of you seem to have a good handle on genetics, what resources to you recommend for someone just getting started? I am interested in exploring some crosses in the standard sizes and I have a variety of birds to start out with as I am also looking at birds on the endangered list as part of my project to breed true.

No, they will not. What we have known previously as 'chocolate' in the standard is dun. Like the OEGB and polish are in the SOP as 'chocolate' but they are dun. I know there are folks with true chocolate in orpington (jumbo bantams), araucana, ameraucana, wyandotte, and I think cochin as well.

Seramas also have true chocolate.
 
Sort of a pale to medium taupe. Chocolate is darker, but both fawn and chocolate (dun based, not choc) are heterozygous dun. Typically different e-alleles (fawn is wildtype: e+; chocolate is E, E^R or e^b). Fawn has silver ground; chocolate can have either gold or silver. I believe that gold gives a richer more chocolatey hue than does silver.
