Cucco's Revenge Squad

A large group of indestructible Cuccos that will attack Link if he causes sufficient harm to a Cucco in the Legend of Zelda series. In The Legend of Zelda: Ocarina of Time, they appear wherever their more peaceful cousins can be found - Lon Lon Ranch, Kakariko Village, and even the bend in Zora's River. The only ways to escape the murderous group of poultry are to leave the area (they can't follow) or to mount Epona (Link himself becomes indestructible).

Failure to do one of these two things will swiftly result in Link's death.

They also appear in both the Light Overworld and the Dark Overworld in A Link to the Past, where the best option to evade them is either to enter a house or not to bully a Cucco up to 30 times.

In all three of the eight-bit Zelda games for the Game Boy and Game Boy Color they also make a return appearance, helping to aid their injured bretheren from further harm by a "certain" hero.

Besides possibly ReDeads, they are probably the best known of all Legend of Zelda enemies. While they were missing in Wind Waker, the pigs found in the game served the same purpose- if provoked too much, they would attack Link.

Cucco's revenge squad seem to mysteriously disappear in Twilight Princess, as attacking a cucco many times will result in being able to control the chicken for about 10 seconds. The reason for the Revenge Squad's absence is unknown. However, the change may not have much meaning behind it - except that almost every aspect of Zelda underwent a transformation during the development of Twilight Princess, from the "evolution" of the Boomerang to the Gale Boomerang, amongst many of the other changed, familiar items, to the complete replacement of the Moblins with Bulblins.
