Candled eggs? Advice needed.

[Silkiesaz]

I'm sorry for how little information I have. My duck Nugget got some chicken eggs a little while back, I don't know when. I candled them and I am stumped. I don't know what I'm seeing. 1 egg got kicked out of the nest and it was cold. I gave it back to my ducks and then added 5 more. Here are some pictures do you think they are alive? Egg 1,
Egg 2
Egg 3

Egg 4


Egg 5


Egg 6

How long has she been sitting? They all look like infertile or dead.

Uh oh. I think about 1 week give or take.

All eggs not viable, sorry

All eggs not viable, sorry

Okay, since she has only been incubating for a about a week can I swap them out with other fresh eggs? Or should I give them to my other duck that went broody yesterday?

You can but chicken eggs sometimes don't do well under ducks.
