Chicken

Chickens are a species of poultry who have appeared throughout the Donkey Kong series as mostly enemies and on occasion characters. In the Donkey Kong series, only two actual chickens have appeared and both are anthropomorphic (aka sentient and intelligent), however other subspecies of these birds often appear in the series as enemies. On Earth and even Mushroom World, Chickens are harvested for their eggs and meat which are quite delicious, but since the dominant species of Donkey Kong Island are the fruit eating Kongs, Chickens have very little use as food there, but they may be eaten by other carnivorous species native to the greater Rare Island Chain.

Diddy Kong Racing
In Diddy Kong Racing, a single Chicken by the name of Drumstick makes its debut as the first Chicken in the series. He is an unlockable character with good stats who was turned into a Frog by the evil Wizpig. After the spell over him was broken, he joins Diddy and the gang in their fight against Wizpig. Drumstick later returns in the remake Diddy Kong Racing DS with the same role and stats as in the previous game.

Donkey Kong Jungle Beat
In Donkey Kong Jungle Beat, an odd species of chicken/plant hybrid known as Chicken Weed appears in the game as a recurring enemy. This massive creature's odd appearance belies its vicious nature and will attack Donkey Kong if awoken.
