Hi just popping in to add my $0.02. Notice how your larger duck has the thicker neck? My Jumbo Pekins are identical to that. On the other side, your smaller duck with the thinner neck looks exactly like my regular Pekins. But to further complicate things, I can not see much difference between all 3 of my ducks (jumbo & regular), but the drake, well he was really jumbo so always easy to tell him apart.
