I use silhouette decoys amongst my spread. They give the appearance of movement as the geese fly by and the view changes.You may want to consider Canada Goose silhouette decoys instead of shells. Silos are much easier to transport, deploy, and pick up. My go-to decoys have been silos for over 15 years. They work !! I stack about 100 silos (home made) on a rack on the back of my ATV. I pull a Jet Sled with blind(s) and other gear. Totally portable in just about any mud conditions, and a light enough footprint that farmers have never not said no to me.
