I read a website about taming agressive Roos. They lady would hold them securely and then place her hand over his face bending his head downward into his chest, holding it till he settled and no longer attempted to look up when she released his face. I personally have done this with all my hens and my roo. Worked like a charm and I continue to do it every so oftern to remind him. He is 5-6 months old now and starting to show a bit of agressiveness to the hens to keep them in line I suppose, but does not attempt to be agressive toward me, my children or my dogs. He roams our fenced backyard all day with the 2 dogs and I am also out there working around. They have all been held extensively though since they were just fluff balls and I still hold them now and then to keep them tame. I pet them at night when they roost and on occasions I will go out and get my roo early in the morning when he starts to crow to hold him in my lap to let DH sleep in. The other morning he sat in my lap as I petted him for two hours till DH got up. They are not afraid and come right up to you. They eat with the dogs right out of their bowls while they are eating. It's quite comical. I attribute their being unafraid to being held and also being around us daily. According to the website article, this method of taming roo's should work at any age, but preferrable sooner than later. You can find it under a simple Google search. Good luck and be blessed ;o)
