How far along are these eggs?

Woke up to find that my duck had eggs, how far along do you think they are? One was cracked so I opened it and it had a yolk inside. So I’m guessing not too far but pretty far. She is not an egg laying duck, and we have a drake.

Those don't look developed to me. If your duck is not broody, then the eggs are not going to be developed anyway. All eggs have a yolk, so if you crack one open and it has a yolk, that is totally normal.

I'm a little confused. Did she lay one of those eggs today, or did you find her brooding today? All eggs should have yolks

if she is brooding them, did she start today? If so, they're not developed at all, if fertile in the first place.
