Deleware were sports from broiler crossed of New Hampshire and Barred Rocks. White feathered birds preferred for broiler industry due to cleaner carcass so these sports were saved and bred to standard, later were crossed back to New Hampshire for broiler market. Both New Hampshire and Plymouth were the Meat bird standard and were crossed for the effect of hybrid vigor and faster growth.
With a mixed backyard flock you'd be selecting for both length and width of bird. Length lends to better egg laying potential and width for meat potential. Both the New Hampshire and Plymouth Rocks are long and broad, heritage stock is. Birds that are lanky you'd not use to breed forward and any birds that laid poorly when mature you'd not breed forward either. Over generations of strict selection for breeders you'll end up with a good backyard dual purpose bird even from your starting flock.
Basically, if you hatch enough from your Deleware over Barred Plymouth you'll find a few that grow faster and larger than the others- both sexes. Pick from the best of those few for breeders.
