My chickens were fine this morning. Their nipples were frozen but they came loose with a little wiggle, no big deal. The water was still nice and "warm", relatively speaking. The temperature in the coop was 12 degrees above the outside air temp. Not too bad for being a sucky coop. It's possible there could be a little frost bite on a comb or two. It's hard to tell at this point. Fritter (BO) with his huge comb and man waddles, I wouldn't doubt at all. Poof (BO) has a pretty large comb as well and it was a little pale at the tips. We'll see.
There was a beautiful sunrise this morning, complete with sun dogs. I tried to take a picture of it but it's sort of faint, look on both sides of the sun about 1/4 of the way in on both sides of the photo. You can sort of see them, thanks to photoshop, but it was much more impressive in person. My kids thought it was neat.
