Another point of interest- I'd love to hear what color eggs your girls are laying! My friend has a black show quality girl that usually lays dark brown (like maran dark brown) eggs. Anyone else? Her's came from Glen See, so they are not mixed.
Mine only laid the cream colored egg; they were buffs.
My light colored girls lay a lighter egg - not a bright white but a light cream. The darker girls lay a darker egg - almost a light brown. All those below with the exception of the blue eggs are silkie eggs. This was before my darkest girls were laying and the camera flash has washed them out some, but you can see color variances.
