Same.
I have heated buckets in the stalls & a sinking de-icer in the 50gl barrel that serves as a trough outside the barn.
My frostfree hydrant is inside the barn, but I water bucket-brigade style so I don’t have to worry about a frozen hose or hydrant.
My stalls are open to the paddock & pastures year-round, including Polar Vortex weather.
I pick a couple piles from each stall every morning, that tells me they are not spending a lot of time stalled overnight - their choice.
I put out flakes of hay in both pastures & in front of the barn for them to “graze” as grass is under snow.
This morning is Day 1 of a weeklong deepfreeze & the barn was comfortable for me & horses. Bright sun helps a LOT!
I blanketed last week when we had heavy wet snow that soaked them through on their backs. Blankets came off when they were dry beneath them.
I may blanket tomorrow night as Sunday is supposed to be the worst - single-digit daytime temps & subzero at night. But I will let horses tell me if they need blankets.
I do a 4-Point Check for body warmth: flanks, belly, brisket & ear tips. If all check out warm & dry, no blankets no matter how cold it is. Unless heavy snowfall or wet, windy weather.
This works for 20yo pony, 18yo horse & 6yo mini.
For myself, layering works to keep me warm. Thermal longjohns under sweatpants, polarfleece top layered with t-neck, warm socks & waterproof boots, gloves & I am good to go for the 30-45min it takes me to hay, grain, pick stalls & refill waters.
If it’s not nosehair-freezing cold, I also spend some time sitting outside dispensing treats.
