Silkies aren't supposed to lay blue eggs, are they?

The green queen is a good example of early generations of silkies bred with Ameriaunas (without a consistent look). The standards for purebred is determined by the American Poultry Association (APA). This is very basic without requiring a DNA test-if a chicken breed meets the standards, then it is considered purebred. Also if a mixed chicken is accepted by the APA (only after showing consistent traits), then it can be considered a new breed. There is always a chance of causing unhealthy recessive traits with "in-line breeding" to closely related birds, but it is how breeders end up with "purebred" consistency for certain traits. Many tried to project this type of quest for bantam satins. So far the silkie cochin mix (aka frizzled satin, smooth satin, frizzled silkie) must look like a silkie with solid feathering in order to meet the standard.
