Every summer a pair of Hooded Crows raises a couple of hatches at the farm, so we go from two crows to about a dozen by fall. The first batch help to raise the second. Since the dogs at the farm are free fed a local kibble that is primarily dried fish (dogs love it and the Omega oils help keep them young!) the crows have essentially an inexhaustible buffet. I find them perched on the feed tray every morning. Today a neighboring butcher gave me a bag full of veal bones for the dogs and the crows are nibbling on any unoccupied (dog wise) bones.
