So sorry for the other babies. How old is the juvenile duck now? They really should be the same size and do slow introductions. Do supervised time to getter and work up from there.Anyone have any advice for introducing a lone duck into a flock? Not a huge flock, just a drake and a duck, but the drake will NOT accept her. I tried today since my pekin has gone broody and he has no one to hang out with while she's on the nest, but he will accept the juvenile khaki cambpell duck I'm trying to introduce. She was supposed to have friends, but unfortunately there was a flood in her brooder when a waterer broke and all the others died. He's been able to see her for over a month now since she's just been living in a different coop with my ayam cemanis.
