Those are girls. You will hear a big difference in them if one is a boy. Some ducks take longer to lay than others but 5 months is in the normal range. A male will have a curl in their tail as well. Size isn't really an indicator nor is color for fawn and whites.
Hi, I seperated them for 3 days---& got an egg from each; they r both hens!! YA! Now I will look for a drake! U were right on the sexes. Why do u think it took the one hen so long to start laying? They r both 9 mons old & the other hen has been laying eggs for 5 months.
