Med City residents are voicing their concern about the goose egg addling process A fragile topic in Rochester that's ruffling a lot of feathers - addling goose eggs. Posted: Apr 15, 2021 9:46 AM Posted By: Madelyne Watkins ROCHESTER, Minn. - Lots of people showed up at Silver Lake on Wednesday, voicing their opposition of goose egg addling. That's where the eggs are tested to see how old they are and the younger ones get coated in an oil to prevent them from hatching. The Parks and Rec Department started this process at several parks in town to help mitigate the goose population. Experts say this is the most humane way to control it, but others say they're not thinking about the history of Rochester. "This was a man made lake and they're trying to destroy that," said Rochester resident, Mike. "And at one time they were thought to be extinct. And here they are, some people probably not even from this town destroying habitat."
