The use of other chemicals or breaking the eggs would result in the geese simply laying more eggs, said Coryer.
"This way, they'll still sit on these eggs and instinctively feel like they can still hatch these eggs. And, when it gets late enough in the season, it reaches a point where they stop laying because it'll be too close to winter," she said.
The oiling process is just one method the council is examining to control the goose population, said Coryer. Previously, the town has sprayed another environmentally-safe solution on grass surrounding the beach that the birds find unappealing.
However, that has not completely solved the issue of nesting at the beach, said Coryer, adding the council hopes to have some sort of solution in place before the geese are expected to return in May.
"When we've talked about the geese problem in the past, we haven't gotten anyone saying we shouldn't [control the population] because they're so plentiful," said Coryer. "It's not like it's a bird that there's a chance of them becoming extinct."
