Cuckoo pattern is different from perfectly aligned bars

The American Dominique archive explains cuckoo as the coarse, irregular barred pattern described for Dominiques. It contrasts this with the more regular, aligned appearance breeders seek in Barred Plymouth Rocks. Looking at a single feather is only part of the comparison: overlapping feathers change how the finished pattern reads across a bird's body.

The account distinguishes a clear boundary between light and dark bars from a requirement for stark pure black and white. It also describes how unequal or angled bars can produce an attractive whole-bird pattern while overly aligned bars form a different visual effect. Some of its suggestions are breeder interpretations, and the writer acknowledges uncertainty about reproducing every desired feature genetically. This is useful evidence of fanciers' observation and selection practice. It should not be presented as a fully resolved molecular formula for Dominique color.
