OK, so I guess I am a little over-the-top with my my small flock of 5 "girls" that I have had for almost a year now. I have a wonderful Amish built coop with attached covered run-very strongly built and we made the whole thing pretty predator proof, as we dug down several feet to install a "sandbox" for the coop to sit on (coop is raised off ground). We also have an electric fence all around it. We are adding a lovely extension run at the moment, for more room for chickens to run around in and interesting things for them to play with. This also has electric fencing all around-the predators do not go near the coop and run. They seem to sense the danger of the wire, and once any curious passerby is "hit" they seem to warn others-ha!
Anyway, we started out with a regular pop door that I would go out to open and close every morning and evening. I'm an early riser, so it was no problem in the morning, but sometimes in the evening in summer (dumb DST), they would want to stay out longer and resisted going into the coop when I was ready to close the door, so I left the pop door open all night, since the run is secure.
As fall (and the thought of cold Indiana weather) approached, we decided to purchase an automatic door that opens at first light and closes when it is dark. We got the Pullet Shut Automatic Chicken Door, and I cannot say enough good things about it

It works on a battery, has a photo sensor that performs perfectly! My girls are roosting well before it closes, but it has a feature that opens one more time for stragglers to come in then closes for the night. It also has a magnet override in case you want to manually open and close the door for any reason. Keeping the pop door open all the time is fine, especially with a secure run, but this past winter, with wind chills at -25 degrees, I wanted the coop door to close at night, for sure.
Also, my very talented husband rigged up a simple sensor on the door that lights up a small light under the coop when the door is closed-I just have to look out the window to see when the light is on or off to know if the door is open or closed. That wasn't enough for me, because I wanted to know for sure that all five girls were in for the night. So we installed a baby monitor camera in the coop. We couldn't get WiFi out there, but the monitor is bluetooth and it works fine. We have the V-Tech video monitor with 5 inch screen and a wide angle lens. I just turn it on and watch (and listen to) what's happening in the coop. I can see when all 5 girls are safely tucked in for the night. It also shows the temperature in the coo[.
I guess I'm a worrier, but this set up really is wonderful-for me and my chickens! I know it is pricey, but I am lucky to be able to have the fun of chickens without
some of the worry-there's still enough to go around!
