youll be lucky, i live in norfolk and a few years ago there were 3-4 people doing it but last year noone is interested, a goose is only a big duck give it a go cause its going to get harder to find someone. There are a few ways to kill it but the easy way is a good sharp meat cleaver, but a bit bloody, you are allowed to use an air gun, fire point blank up under its chin upwards into the brain area, hold the bird by it feet so the head is on some soft ground for the pellet to end up in. its a 2 man job. its cost a few £s for someone to do it as they will need to be machine plucked useually and waxed.
