It's not really a hybrid, in the sense that each cell has a mixture of chicken/duck DNA. They used premordial germ cells (PGC), which are basically cells that can differentiate into reproductive cells, among other types - so it's more accurate to describe the duck as having a mixture of discretely chicken and duck cells, they are chimeras. Only 30% of the PGC's transferred actually ended up in sex organs, so the duck might have chicken cells in its brain and other organs. But it's more or less just a duck with chicken sperm. What's amazing is how they accomplished this without any genetic modification to the duck or chicken - the two species are compatible enough for this to occur naturally.
