I have a 2 1/2 yr old Pekin female. She lives with the chickens. I now have a 4-5 week old pekin duckling. She's been outside in the chicken tractor and is doing well. Has some size to her. Feathers are coming in. She's quaking - no more peeps from her. I wonder if I can introduce her to big bird yet? I'd like to bring her into the coop tonight where I have control over activity and see how big duck reacts. What age have you introduced young ducks to flock? Thanks in advance.
