Crowing
The idea is to make sure they know that the coop is the safe place. Basically you'd be re-training them. Plus... I know you said you checked for hidden nests everywhere, they can be VERY sneaky. For all you know, they could be laying and eating the eggs. Having them "locked up" for a few days would be a good test. I don't think chickens can "hold it" so I wouldn't worry about that.
As for your entertainment, I feel you! I can't free range my group because of the massive amounts of predators but sometimes I bring a chair over and watch them in their coop/run.
