Success!! Thank you everyone for your comments, particularly Quail Hill. Tonight we resisted going down to the coop to do the nightly "herding" until the sun had totally set and the sky had darkened. We tiptoed to the run and all was quiet. We lowered the coop door and flashed a light into the run...not a chicken to be found. They had all settled into the roost for the night! We, too had been giving them just a little too much attention at "bedtime". A couple more nights like tonight and I think they'll have it down. So much easier!!!
