How long for Rouen ducklings to hatch in incubator?

I started 6 duck eggs on 4/8. Just wondering what day to start lockdown?

It's 28 days give or take a few, but as far as lock down can't help since I don't use a bator. but maybe me answering your post will get someone who does to respond

Lock them down about 3 days before hatch..but candle them about every week or 10 days..and as it gets closer maybe a couple days sooner because like miss lydia said..it's give or take..like i have a cuyoga that isn't due to hatch for 5 days..and this morning i look in the bator and he's already pipped..i can see his little beak so hes an early starter..i candled him about 3 days ago and thought he was right on track but surprise! lol So lock them down in your case in about 3 days or so since you're at day 22..and up the humidity.
