Stupid Birds won't come out in the snow - the food and water is under their coop! I tried shoving them out by reaching in through the nesting box door. Lots of noise, scramble out on the ramp but scoot right back inside! I've been out every few hours to break up the skim of ice. Atlanta got 2-3 inches last night. Sheesh! The main door is iced shut. How critical is it to force them out to get to their feed and water? I haven't seen any footprints in the snow yet except mine.
