Do free ranging ducks come back at night?

Also, most domestic duck breeds live around 9-12 years on average, so 2 years is less than ideal :/ I kinda think having a temptation like an open lake is a big risk for pet ducks, especially since domesticated duck breeds don't have the means to defend themselves that wild ducks do. In your place, I'd try to figure out a nice big run situation for them where they can be safe and secure.
