When candling, shell shows speckled?

[Parson's Wife]

When I candled my eggs, though the same on the outside, I found the shell looked speckled, heavily, on 3 of the eggs...I thought I read somewhere this was not a good egg. I can't find it. Anyone? These eggs show an embryo formed (veins, dark spot, etc...)
I would like any info on this. These are brown eggs.

Usually it means the shell is porous. I've read that the chicks won't hatch, but that's not what I've experienced. I had two of those in my last hatch and the babies came out just fine.

Thank you. I was worried about them, and I hesitate to throw out viable eggs if they have a chance.

Gwen, I have porous eggs hatch all the time. If they are growing don't throw them out.

That's good to know. My best looking hen lays eggs like that, and I'd like to hatch some eventually.
