I have six 6-week old Muscovies that have been raised in my garage. I have been opening the door for the past week, and they are afraid to go out. They are also still quite scared of me. Is this normal? My chickens were never like this. They were excited to go outside and were pretty comfortable with me from age 3 or 4 weeks. I know ducks aren't chickens, but I thought they would want to go outside at least.
