Why Addle Eggs?
Treating goose eggs in order to render them infertile ensures that the your resident population of Canada geese does not continue to grow, thereby exacerbating your problems with nuisance birds.
The eggs are treated (in our area) beginning in April. The eggshell is oiled, thereby prohibiting gas exchange. This method is 97% effective, and is the most humane method. (The skewer/scramble method is effective when done by an experienced professional, but is not recommended. Puncturing the egg will result in a foul odor as the egg decays, which attracts scavenging animals to your property. )
Once an egg is treated, it should be marked. The nest should then be revisited two more times at approximately two-week intervals to see if the goose has laid additional eggs. Any new eggs should then be treated, as well. At no time should an egg or a nest be destroyed, as the Canada goose remains able to lay eggs for several weeks, and she will simply relocate a new nest in a harder-to-find spot and lay new eggs!
You no longer need a permit to addle or oil goose eggs on your property, but you do need to register your intent to do so.
Anything other than egg addling, such as relocation or culling, is still strictly regulated and requires that you submit a permit application to the U.S. Fish & Wildlife Service (issuing agency). You must also contact the U.S.D.A. Wildlife Services office located in your state (the recommending agency) to make sure that they support your application.
