We hunt geese a little bit along with ducks but so far typically focus on ducks. I am considering taking the financial plunge for field stuff for geese. Realistically if I cap my decoy purchasing at 12-18 field dekes will that be enough? Is there a good number of dekes that are recommended to sway x number of birds in a flock to land? I realize location is everything but it is also easier to decoy 3 birds than it is to convince a flock of 30. Any opinions would be great. Thanks.
