Thats cute about being watched, i think my girls are broody [they have no eggs under them] so they can bite me. They are both the sweetest and most people friendly of all our ducks but when it comes to brooding they are stinkers. This has been going on for close to 2 weeks now and they are still sitting, they come out 2X a day all puffed up screaming, eating drinking pooping
and swimming, then back into the stall on their so called nest. crazy things, so taking their eggs doesn't necessarily discourage broodiness it just means you won't have any ducklings.
When Daisy decides she wants to brood, you'll deff know the difference.
