Once mine are about a year old, they free range and only get feed during the colder months, when there's less bugs and grass to eat. During the warmer months, they get lots of kitchen scraps and whatever they find in the yard. We live in NC and have a big fenced in yard. There's never a shortage of bugs or leafy plants to munch on and even though our fence is barely holding up in some spots, they've never tried to escape. We have coops for them, but they'd rather perch on our porch. We live in suburbia and I know there's predators out here, but I think for the most part, out yard is too busy with 2 dogs, 3 cats and 3 kids constantly coming and going. We did purchase a fake owl because we've seen Hawks circle a few times and since then, there have been no squirrels or wild birds setting foot in our yard. Couldn't believe how well it worked!
