I've had this bird from a chick he's around 9 months old he has plenty of roaming space In the garden and plenty of hens (5) to keep him company . I'm not very tall (5'2)but I was carrying the eggs from the shed in to the house and he jumped up and started peck me on the feet at first it was cute then he became vicious and started ripping out parts of my hair and pecking my shoulder and fluffing up his feathers . I don't know what suddenly came over him because he was never like this before but is he just becoming "mature" and breeding or what ?
