I have a 5 week old Welsh Harlequin duckling (although she's so big she doesn't look like a duckling anymore!) named Sweet Pea, we named her this because she was so sweet! She was an absolute angel who enjoyed being held and cuddled, and still is for the most part, but has randomly started biting? One night I was laying down with her on my chest and suddenly she clamped down on my lip with her bill, twice! Then another time to my boyfriend, snapped at him between his eye and eyebrow. Anyone know why this habit may have started and how to stop it? We usually just give her a light tap on the bill and say "no". Is it even possible to get her to stop?
