What color will the chicks be from this cross? Just set some of my Maran girls eggs in the bator for a friend and their daddy will either be the Partridge Cochin rooster (Rocky) or my Blue Copper Rooster (Blue). My hens are mostly Blue Coppers 2 are Black Coppers. I'd like to see what rooster is covering what hens (for the most part), I've never actually witnessed my Cochin roo breeding my Marans, I see him on the Cochin hens all the time. He is the top roo but Blue might be covering the Marans since they are the same age.
