How many chickens are actually E Extended Black that appear black? The reason I am asking this odd question is that in my experience, whenever I cross any pure black chicken, or, black barred chickens, they always turn out to be melanised silver birchens, and not E Extended Black. Perhaps I am simply misunderstanding something? When you use the chicken calculator, and you select black, it automatically gives you E extended black. Those results never match up with what I actually hatch out. If I "make" a black bird in the calculator by entering in a melanized silver birchen( which looks pure black), then, my results match up perfectly. I have crossed production type Barred Plymouth Rocks, black Ameraucanas, black Sumatras, White Faced Black Spanish bantams, black Marans, all of these have been melanised silver birchen-not one was E Extended black. Does anyone have birds you are sure are E Extended Black that look pure black? What breeds? What am I missing here?
