The worst sounding turkey calls I've heard came from a real hen. I think she had been injured, or sick. She had a yelp that was a mix of raspy and cough. If I hadn't of seen her when she called, I would've thought it was a person who didn't know how to run a mouth call.

this is quite true, how you call isn't important, when and what are what puts feathers and feet in the air.

Ben Lee once said "a real hen turkey couldn't win a turkey call contest."
