What process defines the feather patterns known as lacing in Wyandottes?

A distinct, contrasting border of color outlining each individual feather.

Lacing is the highly celebrated characteristic of certain Wyandotte varieties, such as the Silver Laced and Gold Laced types. This pattern is achieved when each feather possesses a sharply defined outline, or border, of a color that contrasts clearly with the main color of the feather's center. For instance, in the Silver Laced variety, the background is pure white, and the lacing is jet-black, creating a striking visual effect across the bird. Maintaining this precise pattern requires careful breeding management, as breeders must actively work to avoid 'mossy' patterns where the lacing blurs or bleeds into the background color.
