I was going to get to the female color but am short on time tonight so I will come back to it after we discuss the wing type and male wing color.
Color—Female
Wings: Fronts, Bows and Coverts—silver-gray, faintly barred.
Primaries— gray, very faintly barred.
Secondaries— gray, faintly barred, the outer web stippled with lighter gray and cream.
Here are some female wings. The parts of the wing are the same as the males (i.e. Primaries, Secondaries, Coverts, Wing Bars, Wing Bow, Front, etc.) but the colors are very different.
Below is the wing of a Light Brown Leghorn. The Legbar hen would have barring. Unlike the cockerel the barring is not very crastic on the hen. The barring gene effects the black pigments in the feathers, but doesn't have much of an effect on the red pigments that make up the brown coloring in chickens.
Here is a juvenile wing of an actual Legbar. The leghorn wing above shows the even grey color in the Primary Feathers (this is more brown in the Crele birds, and more gray in the Cream birds due to the Cream Gene diluting the red pigments that make the brown color). The Juvenile Legbar wings doesn't have an even grey color on the Primaries. It show to have some of the Cream/Grey color like the Leghorn Cockerel does about. On the hen the Cream/Gold regions are Stippled (which is described as peppered). So the Standard here is for the even grey color. I am wondering what we actually have in the wings of out females. Again this is the part where you post wing photos of your hens to discuss. I haven't discussed this with any APA judges so I don't know how this is judged, but assume that the stippling on the winds would be a defect since it is not in the standard. I am not sure if it is like the "dark grey" wing bow of the make it impossible breed.
