I've had chickens for about 6 years and today I lost my first hen to a hawk. I let my hens free range in my backyard during the day. This morning I looked out and saw the chickens acting funny, so I went out to check it out and the only chickens I saw were under the grape vines in the back of the yard. The backyard is about 3/4 acre. I then saw one of my Buckeyes laying on the ground dead. I heard the hawks before I saw them. There were 3 of them. I guess I scared them off before they could eat the hen. All of the chicken are now in the run and most are under the coop, even the ducks. I guess that is the end of them free ranging and I now need the put netting over the run.
