So yesterday I needed to kill one of my roos and this was only my 2nd time killing a chicken. I read this article https://the-chicken-chick.com/how-to-humanely-euthanize-chicken-by-dr/ and decided that decapitation would be the easiest. I didn't quite understand the cervical separation method described in the article. I have this knife: https://www.amazon.com/gp/product/B00JPEMNU2/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1. It's brand new and extremely sharp. Yet I was shocked by how much strength and pressure it took for me to cut off the entire head and unfortunately I had a false start causing the bird to suffer more than I would have liked . I'm wondering if there is a better knife or other implement that can be used with the cone? Also if using the knife where is the best place on the bird's neck to start the cut?
