I am looking for some help from the Midwest Coyote hunting guys. What time of day works best for you? Early morning; Mid day; just before dusk?

We have been out mostly mid afternoon to just before dusk. We see lots of scat, tracks, but no dogs as of yet. None of the coyotes have barked at us or made any indication that they have "made" our set. We just have not seen any dogs at all.
We have one of us cover the backdoor, put the Foxpro out by the lead person and try to have the wind in our face or coming in from one of the sides. We have been setting up on the edge of marsh areas over looking small clearings and some fields with rolling hills.

Any suggestions, please.
