I have 13 mixed/pure duck eggs. My ducks are 3 white pekin ducks with a pekin and 2 rouen drakes, 1 crested rouen duck with a non-crested drake, and a silver cayuga duck with a rouen/cayuga mixed drake and 2 roeun drakes. These are how they have grouped themselves off, the rouen pair stays in the yard. I've hatched 6 eggs this year, there are 3 pure pekins, 1 pure and 1 possibly mixed rouen, and a black cayuga (no longer have my black cayugas). Shipping is based on your zip, $6 for the eggs.
