How old are these? 3-4 months? Still too young to tell, I think, but they do have nice foot feathering. Wait a few months, see how the mottling comes in...
im no expert but they appear to be pet quality. backs are to long (should be more U shaped) and combs have to many points, cant see leg feathering well enough to comment on that. Im judging against the photos in the "standard of perfection", my own d'uccles are also pet quality, i have yet to see any in person with the proper shape (the U shape to the back)
