Striation design is narrow, interrupted and light brown distributed evenly over head mantle flanks and  on chest area in lesser degree, dispersed melanin is light beige overlaid on one of the six available ground colors. Beak and feet are flesh colored. Under flue is pearly beige.

 

                MOST COMMON PIGMENTATION DEFFECTS

· Eumelanin design too long or too wide

· Absence of design in flank area

· Excessive presence of phaeomelanin

· Insufficient  dilution on wing and tail feathers
