Non-artificial salt water

[Snipes]

Can ducks go into sounds/oceans/etc that are saltwater? Will this mess up their salt balance because they always try to drink the water they're in. I am going soon to a place where there are large saltwater bodies but no freshwater bodies. Can I let them in the water?

I have seen muscovys in brackish canals but the freshwater is poured into them. I heard that the very top of the water is mostly fresh and I have seen them drink it. Barnacles and such grow on the sea walls so it is salty. I would say let them do as they please they will know if it is safe to drink/swim.

I wouldn't worry too much about it there are plenty of seaducks in the world like the longtail/oldsquaw and eiders so as long as you provide them with the option of freshwater in a dish or something i think they'll be fine. Somebody might have experience with this and can help you out. I wonder about doing a small experiment where you let them have a bit of brackish water just to see how they react, idk just a thought.
