We always hang our birds for at least 48hrs if not longer, don't usually go over 7 days as not got a cooler to keep a steady temp. we hang them in a stable in a vermin proof pen, its always cool in their, we dry pluck when warm and eviscerate about 7 days for turkeys, so the 15th or 16th is D day for our lot. i have plucked a chicken a few days after killing, was really planning on skinning him but when i plucked a few feathers to make the incision they came out so easily i just continued, not tried that with a turkey though.
