Here's a fun thing I just learned from the Encyclopedia of Country Living:
"Margie Minard of Mt. Vernon, OH, told me eggs help those who have problems with deer in their gardens. Her husband read that one of the huge lumber companies found out that deer hate eggs and had developed an eggy spray for their seedlings. She said 'We've just been throwing our used eggshells out here and there in the garden and among the berry bushes and the deer don't come near any more!"
Edit: clever forum software linked my mention of deer to "keeping deer out of your stuff" thread which I will update with this info.

Deer are prey animals and are alarmed by any smell/sight/sound that is different or new. So the answer is that yes, eggs are definitely used as a deer repellent. If you look at the commercially available repellents "putrescent egg solids" will usually be one of the ingredients listed. Now, while deer don't particularly like the smell of egg solids, they are also quite adaptable and will rather quickly become accustomed to the smell if used continuously.
