Have you ever heard any chicken urban legends or stories about chickens you just can't believe? I've heard a few from old timers who have raised chickens. 1. You can hatch a chicken egg if you keep it in your arm pit for three weeks. 2. Anything you place up a chickens vent they will form an eggshell around. (engagement ring was an example I heard) 3. If you feed your chickens alot of alfalfa they will lay eggs with green yolks. If you've heard any please share.
