I have a rooster who is about 4 1/2 - 5 months old. Last week he started doing a funny sideways dance, dragging his wing and puffing up. I honestly thought he was, for lack of a better term, flirting with me. I've read a lot on the subject and believe he is beginning to be agressive. He has also ran up behind me a couple times but has not gone at me. It seems whenever I am outside and they are free from the coop he always has to be doing this in front of me. Last night he did the same thing to my Yorkshire Terrior but he pecked him, AND, tried to do it again today! I've pretty much made the decision to cull him, but a friend of mine told me today that they MAY outgrow it, that he is like a 15 year old boy, but it could just be a phase he is going through. I've only had him since August and it is the first rooster I've had since I was a kid growing up on the farm so I don't know if he will outgrow it or not. I love my roo, but will not put up with an aggressive rooster. Anybody's thoughts?
