You know it's cold when no wild birds are coming to your feeders. You know it's darn cold when your heated waterer is frozen over solid so you have to bring it inside to defrost enough to pull out the ice. I know it's the coldest day of the year as the chickens wouldn't come out of the coop! I threw some BOSS in with them and put hay down from the coop to water dispenser so they aren't walking on ice. Checked the temp at 8 AM and it's warmed up quite well, already at -22F (-30C). I'm not sure how but they say the high today will reach 5F. The good news is this will be the last night of this serious arctic cold that's settled in. The last above 0F night was Sunday. Another night or two of below zero after tonight then finally a day over freezing by Tuesday. Yay! I'll shovel out some more pine chips and refresh with deep dry litter to aid them with this last -25F night. Who knows, maybe I'll salvage an egg or two that's not so frozen solid it cracks open today. The bowl of water I put out this morning while cleaning and refilling the waterer froze over solid in 40 minutes.
