They are definately different. I don't what the fowl necks are, but they are usually longer and skinnier than chicken necks. Maybe guinea hens? I do know that they catch crabs and hold up well

Down 552 for a few miles, bear right by stop sign, make 1st right (green lea rd driveway), red house with lots of stuff in the yard. Go around back. Pay the lady. Get your fowl necks.
