RE: your advice on using calls, scents and decoys.
You can use them all.
Pre rut use urine, grunts, fawn bawls.
Rut use Tending grunts, estrus bleats, estrus urine, dominant buck urine.
Post rut go back to urine and grunts. If you see fresh scrapes then some does are in estrus.
I used a doe decoy once and a buck saw it, he made a wide arch around the decoy and left.
One more thing it looks like you are using corn in the pic. Just to let you know corn is illegal in Alabama.
