Hey there i’m an independent amateur raising 5 chickens and 1 duck, my oldest hen is about 2 and a half months with the others ranging from a week behind or a month behind. My problem however lies in the fact that I now have a female mallard about 3-5 weeks old and I got her with the idea that she would implement herself into my flock and they’d all be friends but it seems mu oldest hen has become territorial and she doesn’t seem to fit in as well as i’ve been told and i thought she would, can i fix this? can they get along and coexist and keep my duckling company?
