Uncle John was in the fertilized egg business when I was young. He had several hundred young layers, called pullets, and 8 or 10 roosters whose job was to fertilize the eggs.
My uncle kept records, and any rooster or pullet that didn't perform well went into the pot and was replaced. This took a lot of time. So, my uncle got a set of tiny bells and attached them to his roosters. He could then sit on the porch and fill out an efficiency report by listening to the bells.
My uncle's favourite was Brewster Rooster. A very fine specimen he was,but his bell had not rung all morning, so Uncle John went to investigate.
Several roosters were chasing pullets, with bells ringing. Well, Brewster had his bell in his beak so it couldn't ring. He'd sneak up on a pullet, do his job, and walk on to the next one.
Uncle was so proud of Brewster he entered him in the county fair, and he was an overnight sensation.
The judges not only awarded him the "No Bell Prize", but also the "Pullet Surprise!"
