Quote:The RIR will produce black chicks or blue chicks. When the birds get older the males will leak non-black or non-blue in the pyle zone ( hackles, back, saddles) the females will be black or blue and some may leak non-black.
The same will be true for the wyandotte.
The andalusian usually carries a gene called extnded black which is dominant over the wheaten allele (RIR) or the brown allele (BLRW). The andalusian also carries genes that extend or intensify black. An example of a gene that extends black is melanotic.
