The best way to kill him is the way you can. What I mean by that is that you do not want to flinch or close your eyes at the wrong time, you need to be able to do the task. I use the hatchet and stump method, but I grew up doing that. I would not recommend someone not familiar with using an ax or hatchet to try it. You are used to using a cone so that makes sense for you. Use your experience.
It's usually pretty easy to get them off of the roost after dark, though it sounds like he will probably fight once you get hold of him. He sounds like a real demon. I'd tape or tie his legs together when you get him. You can try wrapping his wings in a sheet or large towel to help keep him under control. Covering the head should also calm him own a lot. Mainly just be careful and wear leather gloves where appropriate. And enjoy that soup.
