Chicken

Chickens are enemies rarely encountered in the Crash Bandicoot Series.

Crash Bandicoot 3: Warped
Chickens only would appear in Medival levels, where they would flee if Crash came too close. But they can be defeated by shooting them with the Fruit Bazooka, then they will burst into feathers.

Crash Twinsanity
The chickens returned in Twinsanity, in the first level where they would come out of a chicken coop in fencing packed with Nitro. Crash uses these chickens to run into the Nitro to get a Gem in there. Like the previous chickens, they will run away if Crash came too close. They would be encountered again after the player gets out of Cavern Catastrophe, in a large group on a beach. Then they will be later found at Farmer Ernest's farm, in a flock. They are last seen in Slip Slide Icecapades, where Crash and Cortex slide into a chicken-serving resteraunt and three are standing in the back, they can be hit by being slid into, knocking them into the surrounding pit.

Crash Tag Team Racing
Chickens play a major role in this game and have many various roles in the game. In each world (except Midway) Crash can find a chicken in a hidden area and choose a mission to collect all the chickens throughout the world. They are seen in two Die-o-Ramas: Poultry's Revenge in which Crash puts one of these chickens into a cannon and turns around, crouches down, and plugs his ears, only to have the chicken to fly out the back and turn the cannon around and shoot Crash. In Crash Cubes, Crash throws a chicken into an ice making machine and it pops out encased in an ice cube, only to have Crash sucked in. The chickens are seen in the intro, where Cortex, Nina, and N. Gin are chasing Crash, Crunch, and Coco in cars where Coco throws two chickens behind their car and they hit Cortex. They are also seen in the ending, where Crash throws a chicken into the turbine of Cortex's spaceship shredding it into feathers causing the spaceship to maulfunction. They are also targets in a bird-shooting mini-game, and Crash takes one out of his pocket in suspended animation.

Crash: Mind Over Mutant
Chickens appear as exploding projectiles in this game while the 2nd player is in mask form.

Trivia

 * It is unknown how the chickens in Twinsanity got on the beach, these are probably escapes from Farmer Ernest's farm, considering it is right above.
