So my roo is 12 weeks, and so are his 6 girlfriends. I just noticed he is being more aggressive towards them like pecking them on thier head/neck area for what appears to be no reason, just when they are out in their run. The girls will squak and run away from him when he does this. No blood yet. Seems like it is happening more frequently. Prior to this he would just run up to them and stick out his neck feathers at them, which was harmless. Now i am more concerned. Is this just a way of him showing them who's boss?
