Eggs that you buy from the store are probably unfertilized and had no chance of ever turning into a baby anything. Not all eggs are unfertilized, though. Decades ago, it was a fairly common occurrence to buy a fertilized egg. People used to hold them up to the light to check for veins. Now, though, the fertilized eggs you are more likely to come across aren’t chicken eggs, but goose eggs. Canada goose eggs, to be specific. Canada geese are abundant — and not everyone is happy about it. Geese can be destructive and violent. Ask any small child who has tried to feed a goose only to have her fingers bitten. So, what to do?
The Humane Society suggests addling the eggs. Addling essentially means shaking the egg until it’s effectively scrambled enough that it will never hatch. It sounds a bit merciless, but so is shooting the geese.
To quote the Humane Society’s website:
Addling? What and Why? To addle eggs, we treat them or remove them from incubation so they don’t hatch. This is humane if done at the earliest states of development. A contraceptive drug is another way to reduce hatching humanely.
Why addling? It limits the number of geese in places people don’t want more. And it frees adult geese from tending flightless goslings, so they can be encouraged to move themselves elsewhere before summer conflicts are greatest.
