Why is it considered bad luck to bring peacock feathers indoors?

It has to do with the beautiful, eye-shaped markings on the peacock feathers. Many cultures associate them with the evil eye, and to bring the evil eye into your home is to invite trouble and sorrow.

The association between peacocks and the evil eye is illustrated by the Greek myth of Argus, the monster whose body was covered with 100 eyes. He was turned into a peacock, with his eyes all over his tail feathers.

The "evil eye" is the belief that someone (especially witches) can curse you by looking at you in a certain way. Cultures throughout the world and throughout time have come up with various ways of warding off the eye. You can read more about it at http://en.wikipedia.org/wiki/Evil_eye

The peacock's tail is emblem of an Evil Eye, or an ever-vigilant traitor. The tale is this: Argus was the chief Minister of Osiris, King of Egypt. When the king started on his Indian expedition, he left his queen, Isis, regent, and Argus was to be her chief adviser. Argus, with one hundred spies (called eyes), soon made himself so powerful and formidable that he shut up the queen-regent in a strong castle, and proclaimed himself king. Mercury marched against him, took him prisoner, and cut off his head; whereupon Juno metamorphosed Argus into a peacock, and set his eyes in its tale.

I have not heard about this one it's probably superstitious nonsense.

Only if the rest of the peacock is attached.

Zeus had an affair with a priestess and nymph named Io. To hide her from Hera, he turned her into a heifer. Hera figured that out, and sent Argus to tie her to an olive tree and guard over her, as even when he slept some of his eyes stayed open (he had 100 eyes). Zeus sent Hermes to set Io free and slay Argus. Hermes charmed him to make him close all of his eyes, then killed him. To honor Argus, Hera put the eyes of Argus on the feathers of the peacock, her favorite bird. The eye on peacock feathers symbolizes the evil eye, possibly because of Argus's demise.

I always heard the peacock feather is bad luck because the peacock is the animal that let the snake into the Garden of Eden. And because of that act God punished the peacock not by taking away it's beauty but by giving it an ugly call. They have a horrible scream instead of a beautiful bird call.
