Important Scheduling Note. . . Please call us by January in preparation for March/April goose egg addling. During this period, permits need to be obtained and if you have volunteers available they need to be organized and trained. If Home Owner Association Board approval is required, please obtain authorization by mid-February.
Egg addling is the term for rendering goose eggs non-viable, preventing goslings from hatching. Egg addling has a compound effect in reducing the resident Canada goose population. Not only are the year’s hatchlings reduced, but when goslings mature they tend to nest in the same area, adding their goslings to the local population. Additionally, after one to two failed nesting seasons, mother goose is apt to move her nest to a different area.
Various addling techniques exist, including nest and egg removal, replacement with dummy eggs, shaking or puncturing eggs, and egg oiling. Our addling is performed by oiling eggs, in compliance with Humane Society of the United States (HSUS) protocols.
Cost for egg addling is based on service area size and access. Please call to schedule a complimentary review of your site so we may offer a quote. If you have volunteers available to assist us we are happy organize and train them into work details to cover more ground in less time.
Steps to Egg Addling
Locating Nests Geese construct nests in a variety of places, but typically they are found close to water. Islands are very desirable nesting sites. We walk and paddle the area to locate the nests, flag each site and map their locations.
Nesting occurs over approximately one month. At least two site visit are made within two weeks of each other to incorporate early through late nesting.
Addling When nests are located, we perform a float test on the eggs to assess embryonic development. If eggs are in the earlier stages of development they are coated with 100% food grade corn oil to prevent oxygen from reaching the embryo, rendering the eggs non-viable. If eggs are in the latter stages of development, they cannot be humanely addled. The eggs are replaced into the nest and left to develop.
Oiled eggs are also replaced into the nest so the goose continues to incubate them. If the oiled eggs are not replaced and the goose is still fertile, she might re-lay her eggs. It is no longer recommended to re-visit nests at the end of the natural incubation period to remove oiled eggs. This makes for one less site visit and less expense for the property owner.
Documentation For each site visit, we record the location of nests and quantity of eggs addled with summary data plotted to an area map. This information is then used to complete federal and state permit reporting and for future egg addling planning.
Safety Sometimes geese are protective of their nests, but often as not they readily move to adjacent water when approached. Nonetheless, safety for us and the geese is of utmost importance. We work in teams of two for both efficiency and safety. We wear protective clothing and when accessing ponds or lakes always wear buoyancy vests.
We do not use our goose control dogs for egg addling. The dogs would only serve to keep the geese away while we are at the nests and this can be accomplished without putting such predator stress on the geese.
Regulations Two principal regulatory bodies are charged with the protection of Canada geese — the US Fish & Wildlife Services and California state Department of Fish & Game.
The procedures to obtain federal and state permits to addle resident Canada goose eggs are not burdensome, nor do the permits cost money. US Fish & Wildlife Services now has Internet registration. Where registration is required in California, Fish & Game requires a letter identifying the property and anticipated number of nests to be affected.
For Sacramento Valley and neighboring Foothill counties a state permit is required and must be obtained before requesting a federal permit. We can direct you on how to obtain these permits or perform this work as part of part of our service.
