Very interesting...
I left a light on last Winter,, Semi had been clipped in October for the World Show.
She never did get a winter coat that was enough for not wearing a blanket.
It was also a LOT colder, earlier last year.
This year, no lights,, Less blanket time,,, she has grown a pretty nice coat already.
It is also a LOT warmer this year.
*shrug*
Also, having had a very sick horse this year, suspected Potomac Horse Fever (tested negative)
It is thought that May flys may be a cause. There was a documented cases of a night light
that attracted these May flys, the sick horses were exposed to them, grazing in that area.
Who knows???? Always something for me to fret about!
I do keep a light on for foaling cameras. They don't seem bothered by it.
I seem to be the only one not getting sleep.
