Our small place has a eight chicken posse that own the place (free ranging) and follow us around. They came to us after a preschool incubator project hatched them out. If you get a good coop, they will return to it each night. An auto chicken door, opening at dawn closing at dusk, and a self refilling chicken waterer cut down maintenance. I refill their feeder once a week. No smells, or bare soil but the risk of a predator attack.
Oddly, ours never roost outside their coop, and are always on the ground. They are very curious. You leave a door open, they will walk in and check it out. My wife was surprised to find them all in the kitchen.
Chicken poop sweeps off sidewalks if allowed to dry.
No ticks, no snakes, no stinkbugs, fresh eggs, and lots of laughs.
Worth it for us. The problem is roosters, and what to do with older hens that no longer lay eggs. You may need to replace (process, then eat) your flock after a second year, which is really hard when they have become part of the family. We haven't come to that time. Our will probably die of old age, as we get replacements.
