We recently just hatched a mallard duckling 2 days ago and he’s the sweetest little thing. He hatched all alone and has been by himself now for 2 days. Our neighbors just surprised us with 2 new ducklings that are pekin. The mallard duckling keeps running away from the new pekin ducklings and seems like it don’t want any part of them. The new ducklings keep going near him but he just runs away. Is this normal behavior?
