I disagree with a few of the guys on here. We are heading into a cold snap of a high of 5 deg and a low of -25 deg (air temp) with windchills that will be from -60 to -40. I have quite a few friends planning to still go out and give it a shot. Though coyotes do have to eat, they think about SURVIVAL first. They need to keep warm and expend less energy to reserve their fat on those nights. They don't like the blistery cold either, but they do what they have to do to survive. Coyotes, like other mammals, can go a week or better without ANY food - but like any other mammal, they'd prefer to eat daily, although when they are living in such a harsh environment, they'll choose survival over a meal. I'm no wuss to cold temps, and I'd be out there to brave them, but I am a stickler about wasting my time when I could be in the shop being more productive than freezing my sack off and going home with a wind burn and cold. Even drinking beer would be more productive than some of the cold snaps supply for the outdoorsman.
Just my 2 cents, take it or leave it...
