Have you considered putting an automatic opener/closer on your pop door? I have mine set on a timer (rather than a photoelectric eye) so I can let them out in the morning as soon as it's daylight. I have it set to close just prior to dark, and will adjust the times as our daylight hours fluctuate.
I think you'll sleep better if you know your chickens are safely locked up at night!
