I hatched three Silkie chicks in March. I know one is a black pullet. I know the other two are pullet and a cockerel. The question I am looking for an answer to is... The blue pullet, is she just the regular blue or self blue? And the cockerel, he is blue, but why would he have the silver hackles? It is almost like a Birchen coloring, but so far, this is the only silver feathering I see. Any opinion about them would be nice too. I have a hatchery splash in there too if you notice her at all. The two of them together. Thanks for you help!
