Fult--Nice photos! Yep, I think decoys can be a great help in getting and keeping the coyote's attention. Motion decoys are probably easier for the coyote to pick up on as opposed to just a stationary decoy.
I have used the Predator Enticer--a nice blob of feathers on a spring that is run by an electric motor. The coyote in the photo below was mezmerized by the flopping feathers and paused in a perfect broadside position for my shot.
It was the same story with this coyote. Flopping feathers, coyote fixes on the feathers and takes a bullet for its efforts.
I also use a stationary red fox decoy. I made this one out of chicken wire and paper machet and used two wire clothes hangers to form the handle on the front shoulders, front legs and the hind legs as well.
And here's another coyote that was totally fixated on the red fox decoy.
When I set up my decoys and use my FoxPro, I set the FoxPro right by the decoy so the sound eminates from right by the decoy. Any time you can get the coyote's attention on a decoy or use en e-caller to get the coyote's attention off of you, you stand a better chance of being able to move your body/rifle into shooting position undetected.
The last time I went out to call, I used a Jack-in-the-Box decoy I won in a contest. Unfortunately, I didn't call in any coyotes, so I don't know exactly how they will react to it, but I'll bet it will get their attention. I just hope they don't attack it and tear it apart!!!
