We use killing cones,bleed them out good, scald them around 135-140,throw them in the whizbang plucker 4 at a time,cut feet off then heads/necks, pull guts,scrape lungs cut off glad at tail,rinse the inside out real good, put them in a tank of slushy water till they get down to 34-36 deg. Remove rinse real good pat dry place in freezer bags refrigerate for 24 hrs or so then eat or freeze.
Some times before we freeze ours we will soak 4-6 in brine for a few days then bag and freeze. Make real good BBQ chickens. i have cut up alot and froze alot whole. If you are looking to save freezer space i would cut them in half and freeze.To me it is not worth cutting them all up, but need some deboned and what not for those dinners with the skinless boneless breast meat YUM !!!! Hot and spicy wings and the classic drumstick dinners !!! So we freeze whole halves and deboned and cut up in pieces. Every way makes a good way !!!
