Don't love extreme heat or cold and neither do my girls. I'd say the cold months are the worst because that's when we're calving, breaking ice, shoveling/plowing snow and putting out bales. You just never know what to expect in KS. This past winter/spring was amazing with only a few really cold days but the year prior we ended up with 5 calves with frostbite. We'll bring them down to the barn & even keep them in the workshop in front of the fireplace but there's only so much you can do. And after a couple unfortunate episodes I pick my battles & don't drive any of the Man Toys so he's in the heated cab (with stereo) of the tractor or track loader while I'm cutting the netting (sometimes ice) on the bales & doing the be-nice work. And we feed cubes with buckets so if it's muddy & sloppy around the bunks there's always the risk of face-planting. Been there. Even ended up in the bunk one time with the cows eating around me (felt like the main course at a buffet). I think I burn more calories in the winter but sweat off more pounds in the summer.
