I killed and butchered 2 of ours now, the worst part is getting the hair off, thought a wallpaper stripper would do the job but no chance, the killing is done in a pig scales just outside the door then I have an electric winch from Aldi that pulls them out of the crate and straight up in the air for bleeding and gutting, You have to do a lot of prep work, like having all your black pudding kit ready weighed and ready to mix as soon as you have the blood, the gutting can wait until this is done.
Once the guts are out and the hair is off I let them hang for a few days to set the flesh this makes the cutting easier ,start at the head end and work my way upwards , lowering the winch to a comfortable working height makes the job easier.
