A video posted online shows a group of ducks invading a New York state CVS drug store while an employee attempts to guide them toward the exit with a Swiffer. The clip, which depicts a Thursday evening incident at the CVS in Saratoga Springs, shows a group of about 50 ducks that wandered into the store through the automated doors and an employee with a Swiffer cleaning device attempting to usher them back toward the exit, the Schenectady Gazette reported Monday. \"There was no serious damage to the store, except for a small amount of mud that the ducks tracked in on their webbed feet,\" a witness posted online.
