Thanks for the extra photos. She is still young and her comb will start getting bigger pretty soon but it will seem slow going, until she starts laying or just before she starts, blammo...it seems overnight they instantly have a comb.
She has lovely hackles. I have copper hackle envy of everyone right now, it is one of my primary focus' in this years breedings.
To touch on the blue being in the background and every now and then a blue pops up.
There must be a blue bird there now and currently being bred or a blue bird cannot be produced.
My guess is that the breeder has a blue bird that is
so dark blue that the blue actually appears black. I have for very near 5 years been working with Blue Coppers and been working with this very dark blue that appears black. I had a male (was suppose to be Black Copper) that was dark blue- looked black and I used him as the patriarch rooster in my Marans, it can still be tricky from time to time discerning the very dark blue from the black.
Blue can vary, from a very light blue... to the so dark it looks "black" blue.
When these very dark blue birds are bred to a black bird they can produce more blue birds that appear black and not knowing how the blue gene works or how to spot it on maturing birds, it is very easy to think they are all black birds.
If this young gal came from Black Copper parents....guaranteed one of the parents is not Black Copper, but Blue Copper. When the breeder thinks one is just popping up every now and then, it's only because the shade of blue came through a lighter blue so it was noticed.
