Oh and i wanted to share something with you guys. When my brother bought his OEGB from this "old timer" what i could do about my aggressive mature cock i bought this year. He would back yup and hunker down if i put my hand in his pen to jump and bite at me, or he would scootch his butt like he wanted to spur me. The guy said to spray him in the face with a water bottle right as they go to do it, i did it a couple times and he is such a peach now! I don't have to worry about him!!! idk if it will work with other agressive roos, but it did for me so i thought i would share! The key is to get them in the face, lol, sounds mean but ya gotta do what ya gotta do!
