Much of a wild turkey’s odd behavior when hunting them that gives the impression they have a sixth sense to avoid danger is possibly (and in my opinion, likely) due to them smelling the hunter. I’ve killed many mature Eastern and Osceola gobblers all over Florida. I’m fully convinced they can smell. I don’t think its the be all, end all, explanation of why they do what they do. But I do think smell is a factor. Watch the breeze direction next time a gobbler inexplicably hangs up on you, alerts by braking strut and raising his head, and eases off in a way not consistent with him seeing you or you calling too much and tipping him off you can’t actually speak turkey. Rule out the other factors, and you’ll likely see a pattern consistent with him winding you.
Study after modern study has shown that the notion that birds generally don’t smell well is junk science from the 1800s. Off the top of my head, I am aware of study that showed that birds can smell the presence of a predator in their nesting area and will abandon it based on the smell.

I bet trappers don’t use wolf urine to cover their scent when trapping. A coyote is not a grey wolf and doesn’t occupy the same place on the totem poll on the food chain. True wolves are a whole other level of apex predator than a coyote.
Like you said, coyotes are small wolves, so if coyote urine doesn't scare them, neither will wolf urine or fur.
I've killed well over 130 gobblers. I've had them downwind within feet of me many, many times. Never had one spook. Sorry, but they can't smell well.
