saw a programme on tv about a poultry farmer that hangs his chickens for 2 weeks, ive done that with ducks and geese but not chickens, will do in future. i have an old tall fridge to hang them chilled, i think you would need them chilled for a 2 week hang in normal weather, he tested them by pressing his thumb into the plucked breast, if it left a thumb impression it was done.
