Holy Crap, I had to thin a few for a buddy and what a PITA they are. Peking Ducks. They go on vacation and before I get the text "Will you do me a favor" and it was get rid of all the drakes.
They are a lot tougher than I remembered. Those peking drakes necks were thicker and tougher than a full grown Canada Goose. I am not going to recommend a small woman that doesn't know how to do it try windmilling one. It definitely took some force to finish one. I could see it not working if you weren't forceful enough.
On plucking, that was a PITA also!! Back feather didn't want to come out and you have to be deliberately forceful plucking. Scalding did work either because they are waterproof. 30 seconds on 150° water doesn't loosen the feather as with chickens.
Lets just say, I would never raise ducks for meat after this.
