I appreciate the feedback! It's interesting that hatchery breeding preserved foot color and a silhouette that maybe, possibly, in the correct lighting and if you squint, has a whisper of resemblance to a classic Jersey Giant. I wonder how many generations it took to lose recognizable breed traits (like that horizontal back), and if they'll lose every resemblance to the breed standard given a few more years. Or maybe they inject fresh show lines into the mix every so often. I have no idea but it would be interesting to find out.
 
edited to add: Not that I expect show-quality examples of the breed from hatcheries -- a healthy chick with some resemblance to the standard is all I ask for.
