Drones to unleash vaccine-laced M&Ms in bid to save endangered ferrets

US Fish and Wildlife Service to target diseased prairie dogs, food for the ferrets, via specially designed drones that shoot the candies in three directions at once

The US government is set to unleash drones that fire vaccine-covered M&Ms in a bid to save the endangered black-footed ferret, a species that is facing a plague epidemic across America's great plains.

The US Fish and Wildlife (FWS) has developed a plan to bombard ferret habitat in Montana with the vaccine, which will be administered via specially designed drones that will be able to shoot M&Ms in three directions simultaneously.
