I have 5 week old pekin ducks and I just put them outside. We couldn't stand the smell as they get everything wet and throw their food around and it rots really fast. We put them in a small chicken coop with a plastic box with a hole in the side so they can have shelter but they don't seem to be using it. It is getting down to the 40's tonight and the rest of the week. Think they will be ok? When did you put your ducks out?
