Today I had sad thing happen. A hawk dove through my der ntting on the top of my bantam run an ripped the head off of my little bantam hen. It scared me to death when I walked up on it. It flew off after getting caught in the fencing. It was a coopers hawk. Someone told me that it will come back until it gets them all. Is this true? If so what can I do to allow my bantams back out in their run? If at all?
