Not sure this has been covered I have my coop light turn on at 1 am. But natural sunrise is not until 7:51 am. I have bee opening the pop door at that time , then the man door at 7 am when I go to work. The feed and water is in the run , it will be -9 Celsius tonight and the coldest temps are actually from midnight to noon. And it will be - 20 and lower regularly come January and February. Should I just leave them in the coop with no food or water until 7 am or keep opening the pop door when the light comes on?
