I am sure there are guide services that do a great job but i have learned a ton by going on a couple of hunts with eagle lakes in othello. we got birds but more i was looking at the set up and calling sequences. youought look into opportunities on base as well. for public land try the pot holes. as said before be where they want to be.
Scout, scout and scout some more. Being on the X is by far the most important part of duck/goose hunting. Decoys can be important but I've killed limits over 3 or 4 crappy decoys many times just by being where the birds want to be. When setting decoys, try not to put them too close together. Bunched up decoys can signal danger to live birds. Leave a fairly large hole/space somewhere in your decoy spread for live birds to land. Ducks generally don't like landing right in with other ducks. They like having a space to land in. Calling is overrated. If you can't call or are not confident in your calling, just don't call. I've seen many duck hunters that couldn't/shouldn't call flare birds with bad calling. Another important thing is concealment. Hiding in good cover and staying still is key to not flaring birds. Also, keeping you face covered or at least not staring directly at birds is important. People don't realize how much their face/eyes glow and birds can see that glare from a long ways. If hunting with other people, it's generally a good idea to have one person be the shot caller. That way you don't have people moving and shooting at different times. Scouting, being on the X and good concealment are three of the main things for successful duck/goose hunting as far as I'm concerned.
