From -30 with windchills to 60 this week. With the windchills ours stayed in, but mostly because I couldn’t supply water to them outside. My stock tanks were frozen solid with a foot-18" of ice (too far from electrical to put in tank heaters).
The heated buckets were fabulous and I’m glad I followed my instincts and bought them this year. Typically our barn stays super cozy, but it just couldn’t keep up with the sustained cold. I also put snow pads on, which we don’t typically need in our region. I just had this weird feeling that it was going to get very cold and snowy this year.
