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!!!!!
