Alright, so I remember this chicken I had when I was a kid: it looked like two chickens merged into one. One side of it's beak was yellow, the other side was dark gray; it's legs were two different colors, and it's feathers were different colors on each side of the body, split perfectly down the middle. It was like some one had taken two chickens, split them down the middle, and then put them back together wrong. We hatched him out ourselves, and he lived until at least adulthood. None of his parents or siblings where like this just him. Does anyone know what caused this, or what it is called? Thanks!
