Yes this probably will bring in some coyotes along with some other scavengers such as skunks,opossum,crows,ravens,magpies,ect. If the weather is cold and food is scarce ther're more likely to hit your bait more often and stay a little longer. If,like I said it's a cold and over cast day they could come in anytime during the day. Of course the very best time(discounting night time of course)is first light and just before dark.
