Zelda franchise strategy guide/Characters/Cucco
A cucco is a chicken-like species, first introduced as a comic element in The Legend of Zelda: A Link to the Past. They are generally just used as livestock, but it doesn't seem like they are eaten like raised chickens would. Although normally docile, if a Cucco is constantly attacked it will echo out a cry and summon a flock of nearby Cuccos to relentlessly peck at the helpless attacker.
There also seems to be rare cases where a Cucco turns a blue shade, instead of a normal red and white color scheme. There are also strange Golden Cuccos in The Legend of Zelda: The Minish Cap which can even jump out of someone's hands when carried! There is also another species that has been altered to fit into the size of a persons hand, and are dubbed Pocket Cuccos.
