i just got 8 blue silkie and 2 white silkie chicks from Bobbi Porto at indigo egg silkies. if i have 2 white hens or 2 white roosters, and i need a mate for the white ones, and i hatch a white from the blues would it be ok to mate the whites from the blues to the whites i got from bobbi or will they carry the blue gene. and if i hatch a few lavender chicks and i mate them what color will i get?
