They used both.
Before they used the choppers people on the ground were used to herd large numbers into corrals, later lines of hunters with dogs followed up. Once numbers started to dwindle they used choppers.
To guide the choppers they sterilized and radio tagged some females and called them "Judas Goats". The tagged goats would be used to locate others since they would naturally herd together and the choppers would be used to kill all but the Judas goat.
80000 goats were killed off of one island.
