We have a 1-year old RIR and a year old Mallard Duck who lost 2 flockmates a few months back. We went out and bought 2 new comets and a khaki campbell duckling. The babies are now approximately 6 weeks old from the day we brought them home from Southern States (who knows how old they were when I picked them up but I'm guessing not more than a week or so). We started a few weeks back by taking the babies in my dog's crate down into the run and letting them with the big girls where they could interact but be safe. Then I started letting them out and last week my hen actually stomped on one of the babies and I intervened. No blood but I think we were both shaken up, since then I have let the babies in the run when I get home from work and the big girls free range the rest of the yard. Tonight I put the babies in the coop just out of morbid curiosity and when the big girls came back my hen zipped right up into the coop. So I put the babies on the roost bar on the other side from the hen and waited. She puffed a few feathers but seemed to settle down quickly. So I closed the door and waited.... all I heard were the small peeps of the babies talking to each other.... I read before that many BYC posters use this technique to integrate the flocks. Then I read the article on integration and I'm a little spooked about the story of one poster who tried to integrate too soon on 3 occasions and resulted in "carnage". Should I go get them and bring them back up into house or let them be and see how it goes? What about tomorrow? Should I leave them be? Hubs has class from 10-12 and wont be home to supervise during then... It may just be paranoid mom syndrome but I really need some reassurance and things to watch out for.
