Chickens have been a part of the Muppet world since 1972, when the first group of Muppet chickens was created for the Tales From Muppetland special The Muppet Musicians of Bremen. They were precursors to the chickens from The Muppet Show, except they had slightly different eyes. T.R., one of the main characters, would later appear on The Muppet Show as well.
The Bremen chickens were used during the first and second seasons of The Muppet Show. In one episode, guest starring Rich Little, a bunch of real chickens were featured, auditioning for Gonzo's dancing chicken act. It was in this episode that Gonzo developed his obsession with chickens.
During the third season, some new chickens were built with more defined eyes. One of the chickens got the name Camilla and became Gonzo's girlfriend. (Although even Gonzo doesn't know which chicken is Camilla sometimes; they all look alike.)
A black rooster was added to the Muppet Show cast during the second season and a little chick during the third season. In one of the first episodes, guest starring Harvey Korman, a chicken suit was made for the guest star; it would later be used occasionally whenever a huge full-body chicken character was needed.
Sometime during the late 1970s, Sesame Street got its own group of chickens, only they are brown. Another difference from their Muppet Show counterparts is their rounded eyes and sharper beaks. However, the white Muppet chickens did make a few rare appearances on Sesame Street. A brown/black rooster was added later.
There is also a small white chicken on Sesame Street with big round eyes. One of its most notable appearances is in Sesame Street 4-D Movie Magic. This chicken was later used in the Dutch co-production Sesamstraat as Stuntkip. The puppet became the recuring character Felix in 2021.
The Muppet chickens usually communicate with squawks, although they are known to speak at times.
The chickens are built without an eye mechanism. Instead, the Muppet builders found an alternative by giving some chickens one wide open eye and one 'relaxed' eye with eyelid; this way, the chicken could change emotions by quickly turning its head.
According to Kermit, "You have to treat the chickens pretty well because they've got a very tough union."[1]
Although Camilla is the only chicken with a regular name and personality, there have been instances where other generic chickens have been referred to by name.
In the audio commentary for "Bohemian Rhapsody," Gonzo mentions that the other two chickens in the video besides Camilla are named Ethel and Stephanie.
In the Muppets Now episode "Fever Pitch," Gonzo introduces, besides Camilla, fellow fowl Priscilla and Miss Stephens.
