If the coop door is not opened at sunrise here, I hear about it and hear about it and hear about it. I also hear about it if I try to get everyone all settled in before full dark. Seems they like to get up to greet the sun and refuse to miss a single ray. I have read where some will wait an hour after sunup and can get them tucked away before the sun is completely down. I think it all depends upon your area and your birds.
I work days and feed my birds at 5am at which time I open their pop door. On my days off I usually try to get out their just before sunrise, so I can sleep in a little.

I open the door around 6am. They start coming out when it gets a bit lighter. I'll probably open the door at 5:30am when we turn the clocks back next this weekend.
I have an automatic door that I set to close at about 8:30 at night. It is very dark by then and all the girls should have been in bed well before then, but I just want to be sure that I have not locked any straglers out. I have a light that comes on in their coop and run at 5AM and the door is set to open at that same thime. I use the light to extend their daylight hours and it has worked very well for me. They are all up by about 5AM and they usually lay their eggs around 7AM.
My wife works at 7:30 and lets the kids out while the car is warming up. If I did not have that wonderful auto door opener I would figure out what to do by reading these threads about the topic.
I keep stuff like this filed in groups. Here is a group on the same subject about auto doors.
