Regarding lacing on the Blue Copper hen compared to the Black Copper hen standard:
Black with red hackle markings but without the Birchen lacing. This is from MOAC, and the French standard.
Hackle: Copper with a black-colored tip (spreading out almost down to the breast).
Breast: Black. This is from MCC
From the FMCA (Australian) website regarding correct (no lacing) coloring on BC hens:
"The hens, which are correctly copper-coloured, produce a very satisfactory proportion of cockerels with an ideal red mark on the breast.
These two colour characteristics have a very strong correlative between them; hens that have nice hackles, and cocks that have nice breasts."
