Zelda cucco chicks demotivational poster

Whatever you do, DON'T DO THE CHICK SIDEQUEST IN MAJORA'S MASK, YOU"LL ONLY MAKE THEM BECOME ADULTS FASTER.
The cuteness is a cover, for inside they're a demon waiting to be unleashed upon those that cause it harm when it becomes an adult.
The cuccos have one major weakness: if you use mystery seeds on them when they're not pissed they'll turn back to chicks. Just don't try it when a swarm is attacking you...it makes them more pissed.
