I've seen that video before. That guy knows what he's doing and I commend his care for the animal and the need for the quickest death. But as he said, it's not so easy to do on a large rooster, and it does require quite a bit of strength. I can't do it because I don't have enough strength in both of my hands to keep a good enough grip on the bird to guarantee I won't slip and hurt the bird, which is why I prefer to use the cone method myself.
Watching any of these processes on video is a good way to get accustomed to what to expect to see, and that's a good place to start for not just learning different methods, but also learning if you can cope with seeing and hearing it, but doing it is still a bit of a different thing. In the video, you're not holding and interacting with the warm living animal about to be slaughtered, you're not feeling the strength and grip required to hold the animal least of all feel how resistant and wiggly it is, and you're not having to feel the crunch of the neck separating or the feel of warm sticky blood on your hands. A video with audio gives us sight and hearing of the process, but once you add in touch and smell, it gets a whole new level of real, which for some people can make it go from "I can do this" to "No way!" I've seen some of the biggest toughest blokes still turn green and promptly vomit at seeing death in real life even after they'd seen far worse videos. So just be aware that being able to handle watching a video might not be enough and it may depend a bit on how sensitive you are to your other senses.
I do my best to never assume anything about anyone, and in saying that, I couldn't assume anyone that reads this, now or in the far future knew more than I was aware of. I think it's worse to assume someone knows something than to assume they don't. If it turns out they do know more, good for them for knowing it, I'm glad they do, worst case scenario I wasted my time explaining something. If I approach it from the other perspective and assume they already know more and they don't, it can quickly become rather awkward for them, can make them feel embarrassed or even ashamed for not knowing. There's also the fact that some people do need to be told things from the most basic level, eg: "turn off the power" before doing electrical work... because it might not occur to them to do that and then they get electrocuted... even though many people would just assume that turning off the power was the first step to take and wonder why anyone would need to say that... so yeah, always better to assume nothing, including assuming some people that read this thread will know nothing. After all, the audience of the comments in this thread isn't just yourself and I, it's also everyone that will come here in the future, and someone else may find that extra information useful. Maybe I should have worded it better and not as if talking directly to you for the whole thing, that was just mental laziness on my part. For that, I apologize if it made you feel uncomfortable in reading it, and I shall endeavour to be more generalised in future with such things.
