They expect to have to look after a few ducklings at the RSPCA centre in East Winch near King's Lynn.
But at the moment they're not just dealing with five little ducks, or ten or even a hundred. Staff are currently taking care of almost three hundred.
The centre would normally expect to see a couple of hundred ducklings over the course of a year.
They care for them for around two months before they're released into the wild again.
