I'm nervous because we've never done a goose before, but I have one gander in my flock of geese who has earned the right to be my Christmas dinner. Is it much different from processing a chicken? Will a chicken cone even work on a goose? This guy is a pretty good sized African goose. He has a knob and I don't know if it will fit in the cone. Should I buy a turkey cone? I know I need to be sure and get the extra oil gland at the base of the tail. I'll probably remove the tail altogether. Anything else I need to know?
