Perhaps something like this clip?
http://www.youtube.com/watch?v=uN4d5YVUqnE. At least for the first three-quarters of the clip the rooster is putting in a good showing against a much bigger bird.
In the next clip we see peacock vs turkey and Mr Turkey is a much more aggressive opponent.

Neither clip reaches the point of becoming "murder most fowl" though
