Just hatched out 10 chicks from my stock which includes Buff Orpingtons and Plymouth White Rocks. 4 chicks were born with a black dot on their heads and have now developed black/white striping on their wings. They are just a week old today. I thought the white gene WAS the recessive gene and therefor the black striping had been bred out? Some chicks are very pale yellow indicating potential white rocks but the wing coloring has me stumped. Anyone?
