After Ross got rid of his monkey, Marcel, Friends debuted two new pets for the crew that became an even more memorable staple of the show: the chick and the duck. Adopted by Joey and Chandler during the show’s third season, these birds wound up providing hilarity in the background of the group’s lives for years.
Primarily, they are remembered for their habit of watching Baywatch and the time the duck swallowed Ross’ engagement ring. In a weird twist, the chick and the duck mysteriously disappeared during the series’ sixth season and were never mentioned again until the finale, when we learned that they had died, unbeknownst to Joey. Thankfully by that time they were replaced by a new bird duo.
