The times I have panicked were when I didn't close up the run before twilight. I've always closed the coop shortly before or after dark, but if the run is open around that time there's a BIG chance of a predator's walking about early and entering the run and the coop without my knowing that it's even there when I close up the coop. I try to get them locked into the run at least an hour before the sun starts to set. Later I go out to close up the coop's pop door.
It does no good to have a "Fort Knox" run if the run's gate is open, and mine's open all the time that chickens are out free ranging because they have to be able to get back into the run and coop to get water and/or lay eggs.
