During the photo-montage end credit sequence for the 2009 comedy hit, The Hangover, some light is shed on many of the unexplained occurrences that happened during that lost night.
However, I do not recall seeing where the chicken came from, or why they even had a chicken in their suite.
At the risk of answering my own question, I assume it was there to feed the tiger but, seeing as everything else in the film was neatly wrapped up, is there any documented evidence to explain its appearance in the film?
