Fertile Duck Eggs?

[AppMtnChickens]

I have 3 duck hens, a rouen, black swedish, and a golden hybrid 300. They are all over a year and a half, but I have never seen my black swedish lay, and I have NEVER gotten more than 2 eggs a day. But something I have noticed is that my duck eggs are fertile. There is no access for a drake to get in with them, their main pen is completely covered, and when they free range, its supervised. The only one I have never seen using the nesting boxes is the black swedish, BUT "her" voice is that of a hen, and no curled tail feather, and has never had one. So what is up with that?

How do you know they are fertile? if your looking at the spot on the egg yolk, an infertile egg has the spot without the ring around it. ive been tricked by that before

Thats odd! Can you post a video of their voices indevidualy? If you pick one up and walk away with it, it should start to quack loudly

I am not a fan of trying to figure out if the egg is fertile by looking for a bullseye because I agree they are very tricky.
I prefer to just put them in the incubator.
