Our door to the run is always open too, so I don't have to go let them out. It's a very safe run so I don't worry. I usually let them out to roam the yard around noon if I'm at home. We don't let them roam if we're not home usually, unless we leave for just an hour or so. My problem is, sometimes the girls will lay eggs in strange places in the yard! So sometimes I like to keep them close to the hen boxes until they have laid.
