So I have a question it's my first year with chickens. Here it has been snowing/rain/freezing rain and its supposed to get really windy and temps of -25 later. I opened the coop door and they will not leave the coop. The run is 50% covered and totally wrapped in plastic and that is were the food and water is . I know it isn't good to put water in the coop because of moisture (and them knocking it over) and I worry about frostbite, especially at that temp. But I'm worried they are going too long without eating and drinking. What should I do?
