Maurice the Chicken is a chicken who is Nora Dershlit's pet/best friend. Really, Nora is hardly ever out of company of Maurice. He was used in the iCarly sketch The Cowboy and the Idiot Farm Girl who Thought the Cowboy's Chicken was a Sports Car. Maurice, obviously, played the role of the chicken. At the end of a couple of episodes, Maurice is shown and Sam is trying to get Carly to let her eat him (but his name isn't mentioned). He is also mentioned in iStart a Fanwar.
In iPsycho, Maurice crowed into the microphone and it made Sam angry so she said, "Thats it, Maurice! When I get out of here, it's you, me, and a bottle of barbecue sauce!"
Maurice appears again in iStill Psycho.
