I'd vote for letting them out in the enclosed run. At bedtime call them in to the house with a treat. Once or twice will probably do the trick. We're also new to chicken and ours seem to prefer to go in once it starts to get dark. I found it pretty funny that they'd just march on in as dusk fell. If we're on the late side we find them tucked up on their roost. Of course if your and having trouble getting the in, lock em up.
