Anyone use this for making coyote bait?

No but red fox meat has some attraction to coyotes (maybe more a curiosity factor).

I’ve witnessed raccoon in the dead of winter gorging themselves on red fox carcasses.

coyotes kill and somtimes eat red fox i make a paste bait using red fox and it does well for me even have picked up reds using it in hole sets
would definetly suggest putn a good taint to it it develops a good twang to it after 8 weeks
