Now that I take a look at how the tail is heading upwards and the comb is really large, I'd say cockerel. I'm not going to say sorry though- unless you aren't aloud to have roosters where you live, they are very helpful. When you want babies, a wake up alarm, or a protector of the flock. So; congratulations.
