BrownBear1998,
I didn't have as much activity on my baits as I expected when it was really cold and snowy. The most activity was any evening after it had thawed just a little during the day.
The ice and snow melted off here a little over a week ago and the temperatures were in the 40's and 50's some during the week. I think I had the most activity that I have had all winter at my bait. I killed one Monday, Wednesday and another Friday morning. Also, last week they were all taken after daylight. They were at a bait about 1/4 mile from my house and I didn't have a sensor on it so I don't know how much it was getting hit during the night.
Here is the one from Friday Feb. 18, morning:

My neighbor butchered 4 big sows last weekend and he gave me the scraps from them. The coyotes had them all cleaned up except for pieces of the hides by yesterday morning.
He butchered 2 more big sows yesterday and I put out a big mineral tub full of scraps late yesterday but I have not been up to check on them yet.
I know that a lot of guys just take a road killed dear and put the whole thing out at once, but I cut the bones and meat up into small chunks so that even in sub freezing temps. they can come in and pick up bits of scrap to chew on. You can actually make a deer (or what ever meat you have) last longer by putting out small pieces and let them clean it up before you put out more. The coyotes will soon learn that they have to visit the bait site more often if they expect to find much food.
