I don't know if fertile eggs have gone bad. HELP!

HELP!

My duck has gone to nest, and I just candled them. It is around day 18. There is some blue discoloration on the egg, and I cannot see through it, except at the air sack, and a small crescent moon in the egg. There are weird circular things within the egg, and the crescent moon is spinning around as I move the egg. The also smell bad. Not like sulfur at all, but more of a sweet, pungent smell. Please help!

If it smells bad I would remove it before it explodes. How many eggs? Ducks have a longer incubation period depending on the breed ... I'm not familiar with ducks but lets ask some that are.

I do know for a fact, you do NOT want rotten egg to explode, aside from a mess, it spreads bacteria. You could do an eggtopsy on the bad eggs, wear gloves & mask.

What should I look for in a rotten furtilized egg?

 

[Kiki]

It's the inside of the egg is moving around freely when you barely rotate it then it's most likely not good.

Can you shine a flashlight into the air cell side of the egg and get a few clear photos?

An I am still wondering about the smell. It is very faint, and non sulfurous.

Look like it’s is a quitter. Pics are not extremely clear to tell

Duck eggs take 28 days to incubate. Those eggs don't look the best, but in my opinion duck eggs in a nest always stink. I call my ducks my little piggies.

Okay. I also guess I forgot to mention that I am not tending the eggs. The mother is sitting on them, taking care of them. I really do not know how relevent this is, as this is the first time this has ever happend to me.

Wait and check them in a week see if there is anymore growth. Do you see any movement in them now? It might be a small movement, hold real still and watch if nothing turn the egg a little and watch again sometime you have to do that to catch movement
