We think this guy is a barred bantam cochin between 12 and 14 weeks old. We call it "Stripey." Not sure of the sex. We aren't sure of the sex of the black cochins either, but I don't have as many good pictures of them because they don't hold still for anything. Someone has started crowing occasionally in the morning before I let them out of the coop, but I haven't caught anyone in action. I'm hoping it the frizzle roo, and not the others.
