The chick and the duck were introduced in the Friends season 3 episode appropriately titled "The One with a Chick and a Duck." Joey bought the baby chick as a gift for Chandler. After attempting to return the chick, he learned it would be euthanized and he returned home with the chick AND a duck. Over the course of the series, the chick appeared in 18 episodes whereas the duck had a part in 21 episodes. In season 7, the duck became sick after eating Rachel's face cream. The birds were then absent until the Friends final episode when Rachel referred to the pets having died a few years prior but Phoebe cut her off and assured Joey that the chick and the duck were actually at a special farm that didn't allow visitors.
