Egg addling involves shaking eggs or coating them with non-toxic biodegradable food-grade corn oil within 14 days of incubation to make them non-viable.
In the 15 years of addling, greater than 20,000 eggs have been addled which equates to an estimated 11,000 – 15,000 geese directly not entering the population.
Kate Hagmeier, program coordinator, is careful to remind people that management actions target geese that would not naturally be nesting in the region.
Key to success of the program is finding and accessing new nests.
If a nest is on private land, a permission form to access the nest is available on the program website .
