well done you, we use to breed geese but was too squimish to kill them and ended up selling them , big regret! i can only say what i do for chickens and turkeys. stop feeding for 24 hrs, stop drink for 12 hours. try to pluck when still warm as its easier. hang em up by feet and pluck in "rolling" movements rather than pulling so skin doesnt tear. i personally tend to leave them hanging by their feet for a few days (if its cold) til stiffness has gone. have you got john seymour - self sufficiency book? he shows you how to gut them with pictures etc. cut off the feet, as they are dirty.(dogs love these!) you need to cut around their bum without puncturing intestines, i then tye it with string to stop any poo coming out, then slide your fingers inside between intestines and body carcuss, trying to tear the thin membrane that holds everything in place, dont rip intestines tho. go in as far as you can. then start on other side of body. cut off head and neck(dispose of in labrador -ha), find food and windpipe, then start process again, slide fingers between food/wind pipe and carcuss, and loosen membrane from carcus. you should feel up to bit you did from other side them, when its all loose inside gently pull so whole lot come out of neck hole in one piece. dont force/pull too hard or it will rip and leave poo inside bird. check cavity for any "hangy bits" or blood clots, then rinse with cold water, chill and be proud! i keep all feathers cos will make a cushion - one day - ha, and our nursery school uses the flight feathers for arts and crafts! hope that makes sense! good luck!
