Cervical dislocation doesn’t work on ducks?

[Amer]

Wasn’t sure whether to put this here or in the Ducks forum.
I had to cull a half-grown Runner duck with a lame leg today so I tried to do the usual cervical dislocation that I find quite effective for offing chickens.
Unfortunately, pulling on the head as hard as I could only succeeded in peeling the skin right back on the neck, just like if I was skinning the bird. It was a gruesome sight, I could see the windpipe and lots of blood. Pulling more only succeeded in pulling the skin farther back. But the spine didn’t break at all nor did any major arteries so he was still alive, so I ended up twisting the head around until it popped mostly off. Not ideal but it was the quickest death I could give in the moment.
Is duck skin just too taut to use cervical dislocation? Are duck necks too muscular? Perhaps I am too weak to kill something larger than a bantam? What other method should I use?
Is it possible it’s just a Runner Duck problem with their taut skin?

Oh dear! You were using the broomstick method?

I'm sorry about your Duck.

I don't own Ducks, but cervical dislocation *should* work, but it's possible positioning was off or the muscles were too "strong"?

I've found with adult roosters, I have a hard time performing cervical dislocation. Shooting them is what I usually do or decapitate.

For hens, I use cervical dislocation.

No, just my hands, broomstick seems too complex for my smooth brain to understand.

Perhaps.
I still don’t understand why the skin peeled back though. That never happened with my bantams, even when I pulled their heads clean off due to their small size.
