I slaughtered for my first time a few weeks ago. It was difficult and though I had been shown how to make the cut, I kept not doing it correctly. I was sick with emotion. I must have cut into my poor ducks neck six or so times before I finally cut into the correct place. I did the same thing with the second one also, however I learned something the second time. I kept starting the cut too far back and getting caught up on the neck bone. The third time, tears and snot streaming down my face, I made sure I felt the neck bone first and then sliced in front of it towards me. Made a HUGE difference. I didn't have a problem with any of the rest of them after that.
I have so much respect for you.
