Because I've bred Delawares for about 7 or 8 years now and I know what a Delaware looks like.
"Flecks in the feathers" is not what a Delaware has. Just because it's a white bird with black streaks/flecks somewhere does not mean it has any Delaware in it. A Delaware rooster has barred hackles and barred tail. A Delaware hen has barred hackles and tail black, which is black tail feathers edged in white. They have medium size single combs and are gravy boat shaped in the chest. Nothing about those birds is Delaware-like except they have white bodies. In fact, they don't even look like large fowl birds, though it could be the photo. They seem to be very small. A Delaware is a good size chicken, remember it was bred as a MEAT bird when you look at that photo again.
I agree.
