Ground turkey raw in crockpot
My slow cooker manual gives, for 500-800g (1-1.5lbs) of poultry 3.5-4 hours on high.  However I find this one a little fierce, so I looked in an older recipe book.  Recipes for similar amounts of poultry with sauce also come to 3.5-4 hours on high, but assume you brown the meat first (but nowhere near fully cook). This book says to add 1-2 hours if you don't pre-brown the meat.  It also assumes that you preheated the crockpot, if not add half an hour. On that basis I get to 5-6 hours assuming you preheated it, which fits with what I recall from when I used to cook this sort of thing in the slow cooker.
