I' ve coonhunted for over 30 years so I reckon I' ve learned a thing or two about coon behavior. Will they run on sow? Some,especially come breeding season or extended periods of snow cover. Will they be running in 15 below zero weather,not likely at all. Raccoons go into a semi-hibernating pattern during extreme cold. If it was 15 below and you got 43 coon, Id say youre taking them out of their dens.
