Ciphery,
Regarding your decoy spread: Do you have it set-up, so you have a spot for the geese/ducks to land? For example a classic J-hook pattern for duck over water?
Do you sit still with minimum or no movement, while birds are coming in?
Do you cover your face? Camo paint, mesh face masks, or those new thin neck gaiters (I can't think of the actual name right now)? Bright faces and movement scare more ducks.
Do you try to keep your back to the sun?
Calling will attract, but bad calling will scare the birds.
Much of the time, I just hang with my tollers in the blind, and the ducks and geese just come piling in.
For ducks over water, When I am with someone I'll use 18 mallard floaters, a 3 mallard jerk line, a mallard butt wiggler on calm days, a dozen bluebills, 3 Canada goose floaters, 1 mallard robo duck, and 1 baby teal robo duck. When by myself, I'll use 12 mallard decoys, a butt wiggler, and my 2 robo decoys.
For geese in the field, I uses 4 dozen Canada silhouettes, between 3 and 5 dozen snow geese socks, and 2 dozen Canada shells. I'd use full size flocked headed Canada decoys if I had them.
Keep at it!
I've been out several times, been on a hunt with 2 other people twice this year as well, Haven't got a damn thing not a single duck or goose.
I've invested a ton of $$$$ and put hundreds of km on my car scouting areas and going to hunt them. Still have an empty freezer.
