My chickens aren't free range by any stretch of the imagination. They're in a chicken pen with a chicken house in it. Otherwise, the raccoons, 'possums and foxes would have a feast!
However . . . My chickens have a "loafing shed" with perches to sleep on at night if they choose.
Further, every so often, I rake up the pine needles that fall in my driveway and put them in the pen for my chickens to forage in. They love to scratch around and find interesting things.
The other day, I brought a barrow full of pine needles in and dumped it in a large pile. One of my adult hens immediately jumped on top of it and started to scratch. Nah, I don't have to do much spreading.
The teenage chickens (11 pullets and 3 roos) are learning from the adult hens.
Sometimes I sit in my folding chair and just watch them. Better'n TV sometimes.
So, although my chickens aren't free range, they have all the benefits . . .
