@ Donna McCormick, the hens you showed are what is called here in Europe "light Silver Partridges". You can still see the pencelling on the wings and back. In genetics this means they have the ground-color "eb/eb" (= Asiatic Partridge) S/S * S/- (= based on Silver S/S for roosters, S/- for hens because this gene is sex-linked) Pg/Pg or Pg/pg+ (= Pattern gene which is a Dominant gene so it already express (incomplete) in single doses).
@ Birds & Eggs, the Silkies you showed can be considered as (incomplete) Columbians. Here you see NO more the pencelling but you see most black-pigment is restricted to tail, wing pens, feed feathers and should also be in the neck. In genetics this means they have as ground-color "eb/eb" but also possible on "eWh/eWh" (= Wheaten) S/S *S/- , Co/Co or Co/co+ (= Columbia gene which restrict black-pigment to tail, wing pens, feed feathers and neck). This last could als be Db/Db or Db/db+ (= Dark brown which also restrict the black-pigment as the Co-gene except not to the neck = clear necked).
As you can see the roosters come closer to Columbian than the hens which have no more black feathers in the necks what Columbians should have.
