So this is me with my mom's black Muscovy, about 1 year old. He is such a beautiful black bird. One can hug him..like I'm doing, touch him or stroke him but as soon as you turn your back on him, he attacks you. My mom hand raised them (a female as well) and he does the same to her. Why is this and how can one stop him from doing this as I have 10 Muscovies (5 male and 5 female) and none of them attack me.
