Duck acting differently?

[Ratajczykstacy]

Have 3 female ducks, left them locked in their run for 4 days they usually free range but was out of town. They had water and food, not the 1st time I have left them. My runner all of a sudden doesn't want to leave the coop with the other 2 to free range, she is just sitting in her coop on eggs? Should I be worried? Will ducks all of a sudden become broody even without a Male? They are about a year and half old

Poultry/waterfowl usually become broody when eggs are not picked up every day, so when you were out of town, the eggs weren't picked up as often.

Females don’t need a drake to go broody. But since you don’t have a drake no sense letting her continue to sit take the eggs and stir up the nest.
