I have a question. I have a rooster that a friend gave me. I know she bought the eggs from someone on here, I think in a mixed lot. My roo hatched from a blue egg, but he really looks to me like he was supposed to be an olive egger. He has a dark beak and legs with a tiny bit of feathering that look to me like a marans cross. His color I believe is called silver duckwing. But he has a single comb. So if he IS an olive egger, single combed roo, if I cross him with my EE girls, is there a chance I will get olive eggers? Assuming he IS an EE/Ameracauna crossed with Marans like I suspect?
