Don, Out of the three birds above! Picture 4 and 5 are the same bird #90! Maybe a keeper? Only 2 of my Black Copper pullets are showing color and two are not! My two blue copper pullets have no copper showing. I will probably do a blue/black pen at this point. I am thinking next year of doing a solid black pen. Getting chicks from different source.
Just remember that the pure Black colored chicks will not breed true if bred together, they will still have the Copper influence.
