if i buy olive eggs for hatching, and they come to me in an olive color, i know they're not 1st generation (otherwise the eggs would be blue....right? or maybe brown) but if they are already olive, what generation could they be? 2nd? 3rd? etc? and what color will the newly hatched chicks lay once they get to laying age? i want to buy some eggs, but not if they're just gonna grow up and lay brown eggs.
