Right? My barn is deliberately well ventilated so I think the fans are the only possible difference in air quality. I did read an article about pets and wildfire smoke in the Washington Post that discussed livestock and they mentioned trying to find “microenvironments” where the wind direction is changing or there’s a lower elevation. I don’t think blowing smoky air down from the ceiling of the barn qualifies but .
I did leave my boys inside about an extra hour but that’s it. I think they’re better off grazing al fresco than eating hay from nets in a barn with bedding etc. My TB already has some nasal drainage going on. I wore my N95 during chores and driving to/from work and I still feel like crap.
