A friend is raising black silkies. The rooster with the hens are all pure breed. I hatched the eggs last week, and out of the 8, 3 were black, 4 are light grey, and 1 that is striped. Is this normal with silkies? and will the colors change? I also got eggs from the rhode island red hens who mated with the same black silkie. I got 2 of them that are a little larger than the others and are currently Yellow. I wonder how those will turn out.
