This young squab is a cross between a grizzle Birmingham roller cock and a white king hen. These two birds paired up very fast and I didn't have the heart to break them up. I think this is going to mature into a beautiful bird color wise. Does anybody know how the propensity to "roll " in flight is carried genetically and whether or not this bird might possibly do so even though he's not pure bred? That is of course if he doesn't get too big to fly. He is considerably larger than his pure bred roller loft mates already. Thanks.
