Normally, my 'go to work temperature range' is from 10 above to 93 above and that includes either the wind chill index or the THI. Exceptions noted. My clients are aware of those parameters so it doesn't create many if any, problems. Also, since many of my clients are rural, they know that road conditions are also a factor. So, during snow storms and the like, they will call me to let me know what the travel conditions in their area are like. 'Round here, north-south roads can blow shut in the blink of an eye and black ice is an ever constant companion.
Many of the barns where I work are uninsulated metal buildings usually with a concrete aisleway or work area. It has been my experience that in combination, those two things make it even colder or hotter that the actual temperature(exceptions noted). In the winter, once/if my feet get really cold, regardless of the temperature, I'm done. Makes it even worse right now as I'm fighting one of the bugs that are going around and it has laid me low. Been trying to work through it, but between the cold and the bug, I run out of energy quickly so I'm behind right now.
Won't be working next week as I will be in Cincinnati for the IHCS. Hopefully I'll feel well enough to work this weekend. On the up side, unless horses are in a heated barn and being worked regularly, their hoof growing metabolism slows down and hoof overgrowth is not as much of an issue as it is in the spring and summer.
