My game hen just hatched 6 chicks. I have one rooster. A Black Copper Marans. My hens are: 2 Cuckoo Marans (one of which has white earlobes and lays light brown eggs), 1New Hampshire, 1 EE, and 2 game hens (sisters). None of these hens is related to the rooster. All six chicks are black with varying amounts of yellow on them, but not much yellow. I am delighted, but surprised that they are not of various colors.
