It's actually ecologically and ethically better to have "barn" chickens, which live in massive steel sheds on trays with roosting boxes and perches about 50cm high, miles and miles of racking.
They're free to move about at least in their "bay" and have the company of other hens that can wander about too. Sure, they don't get the marketing feelgood "sun on their backs and wind in their feathers", but they also don't get raptors, foxes, or rats.
You can get rescue hens and they're just about savvy enough to figure out - after you've lost one or two - that predators are a thing, and you'll get an egg every couple of days per hen. They'll eat all the bugs in your garden (and most of the herbs, and the tops of your carrots) and shit everywhere.
