Sigrid van Dort suggests that leakage of the red pigment is quite common in white (dominant and recessive) Silkies. Sometimes the colour knock out feature of the white just isn't strong enough to knock out all the red. She describes it as a "buffish" colour. She says the feathers can appear randomly all over the body or be limited to the breast in hens and wing bow in roosters.
I'm curious about this because one of my 10 day old chicks appear this way except it a goldish hue all over, but the base if you will is white. Is this leakage also?
