I don't take the wind chill into account for the chickens, who are safely indoors. I whine about it for ME because I am outside, bundled up like little Randy in "A Christmas Story", cursing frozen latches and electric waterers that are filled with ice. And, yet, I continue to choose to live in Iowa and have outdoor critters.
LOL! That's funny, because that's exactly what I told my husband earlier today, and I live in North Dakota, where it's been in the sub-zero double digits for almost two weeks now, and even worse during the nights. Add that to our prairie winds, and the wind chill gets down to -50 F. We're 'told' that it will break by Sunday, and next week we'll start to see our daytime temps get above zero. Next weekend we're supposed to be in the 30s.
In the meantime, I have my girls locked up, inside their coop... ONLY because we had a predator come in and attack them, lost half my flock, and don't know who/what the predator was. Suspect it was a dog, but never saw it come back, etc. This was back in the fall. Got the fence fixed, re-fenced stapled, but then I noticed with our high winds, it got pulled away again, so I'm NOT risking them being out again until I can get that fixed, and with it being as cold as it is right now, that's on hold, too. They're not minding it, even though it IS butt-cold inside, even with the radiant heater I have running. I've been getting anywhere from 8-14 eggs (I have 14 layers), daily, so conditions are obviously good for them that they're happy and laying. Hubby and I are actually SHOCKED that they are laying so well, considering. Now my only concern is getting those eggs before they freeze, so that means me bundling up like Randy a couple of times a day to check for eggs, collect, and tote in fresh water for them, as it's freezing up too quickly.
