Can duck eggs go in the incubator after then hen has sat on them for a week and a half?? PLEASE HELP

Yes you can move them. I've moved my ducks eggs when they started laying before the temps were warm. Just make sure you keep the cycle for the eggs. If your duck has been getting up and swimming then coming back you may want to mist and cool them everyday. Muscovys are harder to hatch than mallard based breeds so do want to keep an extra keen eye on those air cells and adjust humidity accordingly. This is a great source for Muscovy hatching: https://www.backyardchickens.com/a/incubating-and-hatching-muscovy-eggs
