Scrum slang for someone who is interested in a project but has no responsibility for working on a task in the active iteration. They may observe team meetings but cannot vote or talk.
The term originates from the concept of how committed two animals, a chicken and a pig, are to making a breakfast of ham and eggs. The chicken provides the eggs and goes on to continue producing more eggs. The pig, however, has to sacrifice itself to provide the ham. In other words, the chicken isn’t as committed to the task at hand as the pig even if they do actively contribute to it.
