I have a Black Jersey Giant rooster that has copper hackle and saddle feathers. I want to try a breed for more of this copper coloration. I contacted the lady that I got my chicks from and she assured me that they are pure bred on her end and that the person that she got her flock started from only raised Black Jersey Giants. She also told me that she once had a hen that had some of this same copper coloration. So does anyone know how I should breed for this coloration. Should I breed it back with the pullet that I got with it which is also a Black Jersey Giant?
What if I bred it with a White Jersey Giant would that be better?
Here's a couple of photos of the Rooster in question.
