my girls go through a "secret" door my husband made, into a 5 acre field. They actually queue at the door to get out and make a heck of a noise until I let them out. They wander far and wide but keep coming back ever so often, To check, I think,and they always come back at meal times. at noght they make their way home about an hour before going to bed. they are very clever despite being pea brained with some things.
