When I first got chickens I set my alarm to wake me up at 6.30 every morning (5am in the Summer!) to let them out as I hated the thought of them being trapped inside when it was daylight.
It nearly killed me (I am not a morning person).
Since I fitted an automatic chicken coop door my life has been a whole lot easier. I still feel a little bit guilty if it is past 8.30 am before I get out to feed and clean them and let them out in their larger garden area – but not enough to set my alarm (after all I know they are safe in their enclosed run and have water there and whatever bugs and greenery they can find to keep them going until I get out to them).
I know they are safe, but I still worry, and I still check them every night shortly after the door is set to go down to make sure everyone got in ok and have a little tidy up for them ready in the morning.
And so far the automatic door has worked out really well.
I have had the ocassional straggler left looking at the closed pop hole waiting for it to magically open (I must remember to increase the time it closes every now and then as the days stay lighter for longer) but apart from that the only issue was a couple of nights ago when I found the door had come of its runners and left it so that it could easily have been pushed aside by something.
The coop is in an enclosed run so the chances of something happening if it had been left like that are lessened, but not zero, and that is why I always check it.
