I'm pretty sure our situation is quite different from an urban or suburban yard, but just about every family in our part of the world has chickens and every one has free ranged since birth. There are two families (our next door neighbors) about 3/4 mile away and between them there are about 30 to 40 chickens roam all day every day. They tell me that once in a while a neighbors chicken will spend the night in the other neighbor's coop. I guess it's kind of like a sleep-over.
The only times there are any problems is when a stray dog comes along or when the chickens decide too take a nap in the middle of the road.
