It's likely that almost 1/3 of the nation will have lows around zero or even lower tonight and throughout the next week or so. That will include us as well. Shrug. It's cold. Too darn cold, for sure. But, that said? This equates to 100's of 1000's of chickens that will just get through it.
The blue jays, the eagles, the sparrows and all the other wild birds are in the same boat. They'll all survive as well. They'll just hunker down in a spruce or pine tree somewhere and await the dawn. Not that the day time temps this next week or so are anything to get excited about.
I have probably 50 of those tiny little finches overwintering in my roses and honeysuckle bushes. I have one feeder out they don't seem to use, not sure what they're eating otherwise. But those little buggers are active, healthy and apparently devoted to spending the winter teasing my cats
They sure make cute little tracks in the snow, all over the place. I figure if those tiny guys are okay, my fluffy butt chickens with a protected coop are just fine!
