Back to the original topic, and as a follow up to
Oregon Blues who posted early in the thread and said, "that's what chickens look like" and that they have been bred to such a strange body shape.
If you watch the Christmas film "It's a Wonderful Life" look closely in the scene when George Bailey comes home on his wedding night and his wife has two chickens roasting on the fire. You'll see long bodies with skinny breasts. That's what chickens looked like in 1950, before the advent of the 7-week enormous breasted Cornish Cross.
Enjoy that dark meat!
