Personally....I would leave the vent sexing to very experienced people. I wouldn't want my curiosity to end up costing me a duck by accidentally injuring one.
That drake feather comes in way after the quack vs squeak. Voice sexing is easy once they start quacking or in males more of a smoker squeak.
