http://en.wikipedia.org/wiki/The_Prophet_Hen_of_Leeds "who had written on the eggs using acid and reinserted them into the hen's oviduct." Is that even possible? I imagine it would hurt the hen a lot. Actually, what if there was already an egg ready to lay in her? What if it cracked on the way in? This just sounds impossible. Plus, I'd imaging the hen would die of stress of something trying to do that. Also, I think "reinserted them into the hen's oviduct" is really a euphemism for shoving it back into the hole it came from lol.
