I recently got a new baby duck but the owners lied about her age. They said she was 3 weeks old but shes the size of a newly hatched. I set her in with my current ducks (supervised closely!) For a few minutes, but the other ducks hate her! The geese, guineas, and turkeys treat her like they are their own already, snuggling up to her etc., but the other ducks take every chance they can to bite and shake her neck. I separated her with bricks between her and the rest, but the poor girl is trying so hard to get back with the other ducks even though shes been bitten every time. Right now they can hear her but not see her. What should I do??? Shes meant to be a mate for the very khaki thats biting her!
