I have watched a few random episodes of family guy and in some of them Peter fights a giant yellow chicken. This seems to be a joke they repeat in multiple episodes and in one of them I think the fight went on for around 10 or 15 minutes. What is exactly the problem between them? To me it just looks like they just saw each other and started fighting. Is there any episode that explains how it started, and why it has been going on for so long? Is the chicken just another regular resident of Quahog? I know there is a crossover episode with the Simpsons where Peter fights Homer. Is the chicken fight some kind of Simpsons reference?
In Meet the Quagmires, it is revealed that Peter actually started the fight when he traveled back in time.
The Simpsons Guy features a similar fight between Peter and Homer. However, I have not seen any evidence to indicate that any of the other chicken fights are any kind of Simpsons reference.
