Markings on shells

What do these spots signify?

They look like poo stains to me. I have collected eggs before and when any poo on them that is left for sometime seems to stain the shells like that. I could be wrong but that's my best guess.

I agree. They look a little like floor eggs.

What do these spots signify?

Is this after you washed them?
What did they look like before?
Were they laid in a wet and/or dirty place?

After wash and they came out of the nest box which straw was just changed Saturday

If not a floor egg, this can also happen when 2 eggs come into contact with each other in the shell gland. Normal calcification is interrupted and the first egg may get an extra layer of calcium that shows up in that banding. This can be caused by stress, changes in lighting or disease.

You might look through this poster. You might be better able to figure out what happened.

Some of that looks like there were two eggs in the shell gland at the same time. Some if it looks like something (poo, mud, or maybe even bedding) got in the way of the hen putting bloom on it or the bloom was washed away.

Did you wash those eggs because they were dirty?

 

[fishbone033]

Yes I wash eggs 24 hours after I get them I know of the protective coating but I do wash them with mild soap and brush

And I did forget to turn lights off day prior

Was there poop on them before washing?
Was there any wetness in the nest bedding?
