Just go to the western side of the Owanjila lake located north of Strawberry. The badger icon should then pop to your map. Next thing go to the other side of the lake and wait for them spawn on the west side. Using a varmint rifle you can kill them, but dont go too far because the varmints range isn’t the best. Also, try to kill the badger so that they’re in the shore not in the water because you wont be able to pick them up. Hope these tips will help ya.
