Where should I set some yote and foxy traps
On here the blue line is a very small long field, there's a small creek there. Set a trao there never got one thing except a coon. I seen one coyote footprint there.
Yellow line there's a fence row and somebody caught a grey fox there, fox digged me up there this season but u never see sign and never caught anything there.
Black line is all tall grass the goes down into a bottom, crick is down there too with brush. I don't know hoe I would set in tall grass.

On this picture the farmer says there is coyotes where the red line is but never see sign or get anything. Also a fence row up there. It's a very high field that goes down into a field hill.
Teal line I know stuff is there but I didn't catch anything. Good spots tho.
Yellow line is where I caught my first one.

I would suggest taking a longer view out at the landscape. Size the sat the image so you can see what is a mile or two out first. The idea is to get feeling for how they travel from various points using the terrain to end up where you can trap assuming you arent moving to them. That typical farm ground doesnt really give up sign readily but a track can end up about anywhere as they poke around. Its where the setting on sign saying can sorta get dicey. There isnt much sign to see and there might be one track show up occasionally. Its usually best to find the consistent travel or congregation spots. But sounds like you have sampled a few spots within that fields trying to get a feel for things. Thats what I might do too. You didnt say how long you've been set on those locations without catches and I don't know what your population is like in that area. Keep in mind eastern farm ground can be, not always but often, low on coyote populations in the grand scheme compared to many places in country and that can mean long waits between travel times depending on time of year and what family movement looks like and then dispersal. Additionally, low populations have often been harassed from all levels including trapping, dogs and calling which doesnt make them quick to wanna commit either. Not saying that catches cant happen overnight or even in a 3-4 day window but its possible you are in an area or particular spot where you need to be out for a minimum of a couple of weeks to have a real chance.

Here's what comes to mind when I see from the image---how far does that blue line ditch extend? Secondly, what happens farther out on that red line? Does it go somewhere of interest? Those look like livestock type buildings with dairy stuff in the northern ones. They'll be points of interest but at times they can be real hard to get commitments. So you need to consider how they get there. Look farther away is my advice

Wheres that teal line end up?

If you would like the best advice, find actual tracks or poop and place your trap in that exact location. Not 3 feet away or behind a tree, right where the tracks are. Put your boots on and look for sign, you will learn alot more with your boots in the dirt than you will on the internet.

Best thing you can do is throw that sat image away. Spend a day walking looking. When you get a good snow that will lay on the ground couple days walk your land. Then walk it again.
