I think it's a girl, too. What is it's behavior? Does it "strut", hold it's neck out like it's listening for something? I have a 20 month old cockerel that has streamers and is starting to get his "roo" tail, but still chirps and tries to hide under his female silke friend (half the size, same age) and is scared to death of all the other chickens. The only behavior he exibhits that is cockerel like is his stance.
