One of the "girls" I hatched 16 weeks ago crowed for the first time today. I take it that there's no doubt I have a roo on my hands? It looks like a girl, only now that I've heard he/she crow that I think that maybe it's a little tall. In the same batch I had a roo that crowed at 3 weeks and so I figured it was the only one. Now I'm giving all 5 from that hatch a close look....
