I've had this drake for about two years now. He was penned up for the most part, and was always a little aggressive towards me. Now he is roaming the yard, I feel it's better for him. However, in the last two weeks he has become VERY aggressive to the point where I can't walk in the backyard without literally being attacked. Is there a solution or should I just get rid of him. I'm not that attached to him so I could do whatever. Thanks!
