Thanks for the advice!
We did pull the chicken egg.
A Swedish Blue has gone broody next to her and we have made a new area and home for the other ducks. Should have a round of ducklings in two 1.5 weeks and another in 3.5!
We have a runner that went broody about a week ago, this is our first broody duck, though we've had chickens brood and hatch/raise chicks before. She built a nest in the coop where she sleeps with our 6 other ducks (runners, rouens, a blue swedish and a khaki campbell) and we haven't moved her...
