It’s been mentioned already but some days they just don’t respond (and it sucks!). I Went out and did a 8 mile loop yesterday in my best calling area. There’s no roads around and it gets very minimal pressure. It snowed a little the previous night and continued to lightly snow throughout the day. The only thing that wasn’t perfect was the slight east wind. Our predominate wind is a north west wind so not sure if that throws stuff off a bit. Only a coyote could tell us that haha.
However, I thought it was going to be prime time and I would run out of bullets with all the coyotes waiting to come into my call. I got my butt kicked and only truly called 1 in. It didn’t matter what I played (distress, vocals, fights) they just weren’t responding. Saw at least 8-9 mousing around and they definitely heard the call. They just didn’t want to respond.
My opinion, go back out and hit some new areas. Come back to those spots in a few weeks and try it again.
