Serious faults

Faults

A little brown in the feather-field on breast, belly and thigh feathers. Too much black in neck- and saddle-hackle. slightly mold-color in the wing-flights. Too little pattern in neck- and saddle-hackle, back and shoulder feathers. Shaft colour slightly too light.

Color and pattern female

Head: black.

Neck: black hackle with brown shaft, changing to dark golden-brown with broad shaft stripe towards the body, with the proviso that the outer black lace is so broad that the hackle shows black; some brown in the upper part of the neck is permitted; feathers on the front of the neck dark golden-brown with broad green-glossy black lace and within that a narrower similar lace, parallel to the outer one.

Back, shoulder, saddle, wing-coverts, breast, belly, thigh and body: dark golden brown with green-glossy black doublelaced pattern, of which the outer one, which runs along the edge of the feather, is broader than the inner one, which runs parallel to it; the large feathers of the saddle and those of the lower breast also have a green-glossy black stripe along the shaft, which is also black in place.

Tail: black steering- feathers with the exception of the upper feather on both sides, which is irregularly patterned with dark golden-brown; coverts doublelaced and also provided with a green-glossy black stripe along the shaft, the shaft is black in place.

Primary-flights: inner-vane black; outer-vane dark golden-brown.

Secondary-flights: inner- vane black, outer-vane dark golden-brown, preferably with a narrow black lace on the outer edge of the feather, but some coarse black lacing within the golden brown feather field are permitted. 

Down: dark-grey

Serious faults

Too heavy, irregular, not completely surrounding outer lace. Absence of inner lace. Dark reddish-brown or hard rusty-red feather colour. Too light feather colour. Too much brown in the neck. Strong peppering in the feather colour. Too light shaft colour.

Faults

The same but present to a lesser extent.

Note

When assessing the double-laced colour variety, the colour of the dark golden-brown must be given due attention. An even ground colour is highly valued.

In over-year-old hens, the presence of a complete triple lace is not considered a fault.
