Hi and welcome to BYC - glad that you have joined us. Sorry, I'm pants at gender, but if you post the same pics on the "what breed or gender is this?" forum i am sure that you will be advised by the gender gurus.
BYC has a very useful Learning Center and it is worth reading
I see your concern and he is one beautiful young man that is the way I am swaying right now due to the pointed tail feathers, are you planning to use him in your breeding program as I would if I had such a gorges fellow like that
