The Harlequins were my first ducks, and I clearly remember asking Dave Holderread "How much water do these ducks want?"
his answer was 'They WANT the ocean! ...but will be just fine with enough water to submerse their head in.'
They have kiddie pools in my yard, but prefer to sneak off to the neighbor's koi pond when I'm not looking. Mine cannot fly at all.
Have a ton of fun with your new ducklings!
