Ok this past friday a hawk killed my dominique hen. It was so heartbreaking. Usually I let my hens free range during the day and lock them in an enclosed run and coop at night. The day after the attack the hawk was in the yard all day so yesterday we built an extended run to gave them space where they are safe. The extended run neefs some spaces closed because its chain link fence pieces we buily a pen from. How big of a space can a coopers hawk fit through? Will it stay aroud or leave? Can i ever let my hens free range again?
