Silly as this may be, a friend of mine grew up with a mom that butchered her own chickens. To this very day, 30 years later, she still talks of the "smell". Said "she knew" when her mom was cooking up a raised chicken, there was a certain "stinky" smell that let her know it was from their chicken stock. This has bothered & stopped me from raising meat chickens. I realize all things have a smell, even the fish I clean after fishing but this sounds like a horror story. Maybe the chickens were sick? What say you?
