I adopted this duck which I named Harvey, I had 2 chickens at the time a Gold Laced Wyndote and a New Hampshire Red. They are free range. On Sunday I found my my Wyndote dead with a wrung neck. The only other animal that was outside with her was the duck and my new hampshire. Also Harvey has become VERY protective of the new hampshire and follows me all over the yard. Has anyone else ever heard of a duck killing a almost full grown chicken? She was 4 months old?
