Spots inside egshell, Mold??

[SilverDuck284]

So I collected some duck eggs from near a pond that I wanted to try and incubate. I noticed that some of them have small dark spots on them. You can see them from the outside. One had a lot, so I broke it open and found these dark blobs. The egg looked fine other than that, it wasn't watery and the yolk didn't look too old or spoiled. Does anyone know what this is? Should they be tossed or can they still be incubated?

To me they almost seem like mineral stains.

They aren't smooth, like just pigment in the shell. I don't really know how to describe it, but they are liquid blobs. Mucus-ey looking, might be a good way to put it,

Then they could be fungal or bacterial. yeah. I would not try to incubate them.

I am not a hatcher, it's just my feeling about it.

 

[SilverDuck284]

I'm going to err on the side of caution. But I'd still really like to know if anyone knows what this is. I couldn't find anything similar when I searched the site.

 

[Amiga]

Yeah, kinda makes me want a microscope. Oh, and to know how to identify microbes.

I'm mostly concerned with if its contagious to the other eggs. There were some with the spots, but that one had the most and the largest. I'm a little worried that even eggs without spots may still be contaminated. I'll probably space them out in the incubator and if any start to show up, they'll be tossed asap.

i have never seen this but i think it could be where the ducks ate some thing and that is what is in there egg i don't think they will hatch but let us know what happens to the eggs

 

[SilverDuck284]

There is one egg with two very small spots I'm thinking about keeping. It will be separated from the rest, but I'm really curious about it.

Wondering if there is an extension office with a helpful person near you.
