Possibly, you may need to raise up quite a few.Yes, but, if it's a green egg..does it have the chance if bred to another green egg to be blue? Haha I want some blue eggs!
50% males right off, then 50% females ( this is statistical average; each hatch can vary)
blue gene/brown gene x blue gene/ brown gene =
25%blue
50%green
25%brown
HOWEVER, it is not quite this simple. I know when I asked a person who sold me an anericana what color eggs he was like to transmit, the discussion focues on a sister that made greenish eggs.
Best bet---buy easter egger pullets.
