Hi I have a new flock consisting of 10 chickens (various breeds) and 5 muscovy ducks, 1 male and 4 female. I know some from when my grandmother kept chickens but I know very little about the ducks. My question one of my muscovy hens seems to be on guard watching over the others. She and the drake are older than the other hens by a few weeks. Is this something others have noticed?
