I've read it's 5-10 years but was wondering if it's longer if they are pets and not wild.
I get invaded with these ducks and they seem to live forever! Messy buggers, ballsy too! Nothing seems to deter them from being here. I don't grow them, and don't want them. Friendly yes, but I'm not set up for them. They fly in and poop everywhere. They love my paddle boat, and I don't get to go out when I want since I have to clean it before I go out, plus it stops up the drain holes.
