Note

As the chickens of the millefleur color varieties age, the amount of white in the pattern will increase. Two-year-old chickens generally have the best pattern distribution.

Neck: hackle ocher-colored; each feather ends with a tiny spangle and a golden-yellow ornamental fringe on the sides; front of the neck similar to the breast.       

Back and shoulders: dark ocher-brown, each feather with a diamond-shaped white spangle.

Saddle-hackle: similar to the neck-hackle, with a short white shaft stripe pattern, this is less noticeable because the feathers ends thinner than those of the neck-hackle.
