I have 10 Pekin Ducks and today when I went out to feed and water them and , two of them were picking on one. Only one of my ducks is positively a drake (he has a curved feather) but I'm thinking others in my quack pack are drakes as well but don't have their feather yet? But either way I took one out (an obvious female) because my drake and another were rippi g out her neck feathers. Granted she held her own but I couldn't just watch. I'm a new duck mom. What do I do???
