I went on a course two years back with a vet to learn chicken butchering. Totally worth it. I've done about 20 birds since then and get faster every time.
Still totally slow I'm sure by pro standards but managing to do a bird from start to finish in about 15 - 20 minutes now.
I didn't know such classes existed! We have a couple of friends with chicken butchering experience, plus my mother, so I'm hoping it will be fairly drama free. I want to do it as humanely as possible. I'd also like to not traumatize my children. Haha!
