Black copper should be birchen at the E locus and also gold at the silver locus. Some of the black copper are what I call pseudobirchen- they are actually heterozygous extended black and birchen. It also takes other genes in the mix to make them look birchen. Dark red black copper also carry...

Some males that are heterozygous silver and gold do not show any gold in the pyle region (neck hackles, back and saddle hackles) while other male birds do. In females, they are either gold or silver. No problem there. Homozygous silver males are usually white in the pyle zone. In order to...

Quote: Hurley, There is an extension locus or E locus in chickens but no agouti locus. The 5 most common alleles found at the E locus are; extended black, birchen, wheaten, wild type, and brown. Extended black is the most dominant with brown being the least dominant. Extended black is the...

I am not Blackdotte but I can answer the question. What you have is a blue cuckoo barred (silver) birchen. The male is heterozygous at the silver locus- he carries a silver and a gold allele. The birchen primary color pattern is making the bird much lighter in color than a normal black...
