http://www.sandgpoultry.com/heritagewhite.html sounds like a cornish x with smaller breasts. anyone heard of these?? the site says: The Heritage White chicken comes from the old White Plymouth Rock stock. Its sturdy frame and well balanced body makes it a great meat bird, not like the sluggish Cornish Cross with its giant breast. Our bird is bred to perform outside where it can earn its keep using a keen sense of awareness along with great foraging ability. If you want a bird that’s healthy, grows well with good feed conversion and usually reaches market weight around nine weeks, try our Heritage White.
