Could it really be a hen?!?

I was given a young hen on Labor Day weekend, by a co-worker who took 2 roos off my hands. Last week, I was looking around for my youngest roo (who is approx. the same age as that hen), and found the two of them engaged in sparring behavior. They were facing each other, neck feathers frilled out, heads bobbing, and jumped up at each other. I called my co-worker last weekend to tell him I had gotten a roo, and needed to bring it back and get a hen (this is what we had agreed to IF it turned out to be a roo). He asked if it was crowing yet----no. But neither is my other young roo. But my co-worker said that al his roos around that age are crowing now, and he is certain that I have a hen----he says hens will sometimes act that way (I've never had a hen try to fight with a roo). He says to wait a little longer to see if it starts to crow. I was just wondering if any of you think it's possible that this is a hen? Don't have pics. to post, but I am positive it's a roo---not just because of the sparring, but because of the way it stands and moves. I don't know, I almost got the feeling my co-worker was getting irritated with me for questioning his ability to tell a hen from a roo. Maybe I should just keep the thing no matter what it is----but I really do NOT need any more roos----I have 4 others!!!!!

 

Thanks for the input. I believe this bird is about 4 1/2 months old, and it is a marans-cross. What do I look for as far as saddle feathers----those are the feathers on the back, right? The comb is not that big, but neither is the comb or wattles on my other roo, who is about the same age.

 

Well, here's an update on this situation: the "hen" was a roo. He never did crow, but about a month ago, my roo (who was around the same age as this one) killed him. We found him already dead in the pen, with my young roo standing over him. I tried to tell my co-worker who I got the bird from that it was a roo, but he wouldn't listen. It's so strange how some roos can coexist peacefully, and some just don't fit in-------my 2 older roos have a few minor skirmishes once in awhile, and sometimes chase after my younger one, but there is never any blood drawn. Wonder why that happened with the other one?
