Our chickens are free range. We lock them inside a large covered run with a coop at night, so the coyote's don't get them. Yes, coyotes can get them during the day, but our dog keeps the coyotes and other critters at bay. We open the gate right before we leave for work in the mornings, about 6:30 a.m. Central Time and they stay out until about 8 or 9 p.m. During the winter time we find them already in the coop; probably because it starts to get dark outside much earlier.
The chicks have free range as far as they want to go. We have never found them off our 65 acres. And, as someone said, a washer sprayer is good to have for the porches because the chicks get curious and investigate. Hence, the reason I have only wood furniture on the porch and nothing with fabric.
Over the years some chicks have refused to go in at night and have stayed high up in the trees, as we do not clip their wings.
We have never had a serious problem with the chicks laying eggs any place but the coop. The one time, they laid eggs in an old chicken box in the barn, but the eggs were easy to find and it was only that one time. Don't know the reason for it.
I attended a poultry seminar and the speaker said that the definition of "free range" was one hour a day of fresh air. That could mean, opening a window in an extra large coop or on a poultry farm that keeps chickens indoors all the time.
