Question about split wings in these chickens. How common is it and it is a genetic flaw correct? I have week old chicks that I hatched from eggs purchased from BYC member and out of 6 that hatched I have one that both wing feathers stick out and another that it looks like one side sticks out. Split wing is where there is a gap in the wing due to feathers not present. These birds should not be used to breed correct? Thanks for the help.
