Yea we're on 5 acres too, most of the backard is rocks and woods, the front is grass but they like the back, thank goodness they don't go that far back to the neighbors b/c there's about a 5 acre space seperating us I think.Even though I have 5 acres, whenever I let my chickens out, they insist on going into the one neighbor's yard who can't stand them and calls us up. So now, I just let them out when she's not home, but even then, instead of staying on our property, they are 2 or 3 houses away sometimes. But I can just go outside and call "Hey chickens" and rattle the raisin package and they come running.
