Doesn't the heatlamp give off a creepy glow? Anywhoo, I've been getting frost on the inside of the windows in the coop (well, actually in the house too ), and was wondering if I should be concerned. Our temps have been -15F at night without the windchill. interior coop temps are around 10F above. When it drops below zero, I switched out the regular lamp for an infrared on a timer just to add a little warmth. The bedding is dry as a bone and their water is kept out in the run. I do the lazy butt version of deep litter. Ventilation includes a couple of vents up in the gables that are always open, plus a 2 foot square window that gets propped wide open all day. Plus their pop hole door is open all the time. I was wondering if I am being too much of a worrier on this ventilation issue...Pat's got me all concerned. Thanks Pat Any thoughts from others living in the frozen tundra??? Is a little frost on the window panes NORMAL in these extreme temps?? The frost does go away when it gets a little warmer (above zero).
