I put my chickens in their coop at night. Then I let them out in the morning. I have only lost one chicken to a predator ( A young chicken) he was killed by a hawk. I was very sad. I was afraid to leave home for the next few days. All my chickens free-range whether I am home or not. My roosters have saved the flock from hawks many times. If you have free-range chickens and you can have roosters I suggest getting a rooster. You chickens are much safer with a rooster around.
Good Luck!
