A couple of weeks ago we lost Effie to an unknown predator, so our Magpie "Stinky" has been an only duck (with one turkey and 20+ chickens). I since have bought three new ducklings. Do ducks establish a pecking order like chickens, or is it safe to introduce them to Stinky? Being that it has finally started getting warmer, and I'm tired of having three ducks in the living room, I would like to move them to the outside.
