The Mallard in the back is twice the size of all the other Mallards. This is a MONSTER Mallard and I'm sure his mother is proud..........
The bird is a Rouen (pronounce roan)a french domestic that is said to be the predecessor of all domestic ducks. Years ago when I used to raise some poultry I had a Rouen half breed that ruled the roost and tried to breed with anything that walked or flew.
