I have 2 hens a rooster and as of 5 hours ago I not have a female ( I think ) duck. In their open area there is the chicken coop , I have a kid dollhouse and a large dog igloo that serves the purpose of shelter for them . Well the duck won't go in any of them. She is just wandering around . I messaged the previous owner and she said she would never sleep in the coop with the other chickens , even when the duck was the only one left she wouldn't ..... What should I do? I've tried luring her into the other two area and the coop but she is still probably unsure of me .
