I have only had chickens and that was a long time ago. They always needed a roost at night.
This is my first duck raising experience this time around. At our newer place, we do not have a coop yet for our five 2 week old muscovey ducklings. They are in the house still. Umm, yeah... I want them out very soon. I like to put them outside in the fenced backyard to poke around whenever it seems warm enough. They need a coop for their own safety at night and when we leave for the weekend at times.
My husband and I are not sure if scovies prefer a roost in the coop? From what I read of their habits, I assume yes?
