Do you have any pics of what this looks like? I am considering trying this next year.
It is bitter cold here in northern Minnesota right now, but if I make the time, I will take a few pictures. At the moment, I get in and out of the cold as fast as possible.

I grew up in Minnesota, so cold winters are nothing new to me. However, as I get older, I cannot stay outside as long as I used to when younger. The cold gets down in my chest and I will be coughing for days after. So, I limit my exposure to the cold as much as I can because I need to save myself for snow blowing the driveway if we get hit with lots of snow.
BTW, my lungs got damaged while I was serving in the Navy in an overseas assignment. So, it's not just old age creeping up on me. Not only do I now have problems with cold weather, but I also have become very sensitive to smells after that tour of duty. If Dear Wife puts on too much perfume, I will be coughing my head off, sometimes for hours, until the air clears.
The other day, I was in a store and in the same aisle as me there were a mother and daughter shopping. The younger woman had too much perfume on and I immediately started coughing. OF course, today every cough is a sign of COVID infection, so I quickly went to another part of the store to clear my lungs where nobody was shopping. I don't want to freak people out because some perfume set me off. And it is not like the perfume smell was bad, it was not, but any strong odor can set me off.
If my chicken coop had any ammonia smell, it would also trigger me. So one of my main goals is to keep the coop clean and ammonia odor free. My hypersensitive nose is a great detector in that sense.
