Poop stains on eggs

[Sfowler]

My hens just started laying eggs. They have learned to use the nest box for laying eggs only; however, sometimes their are poop skid marks on the eggs. Is this normal?
If so how do I clean and store the eggs? If this is not normal, what could it be?

That's good.....I assume nests are now clean of any night poops.

Is this normal?

Not unusual.
I have one bird that poops almost every time she lays an egg. SMH.
Post some pics.

It's up to you just how.

I don't wash eggs unless they are very dirty, then will refrigerate or use immediately because thorough washing will remove all the protective bloom(cuticle).

Eggs should be washed in 'water warmer than the egg'.

Simple physics, using colder water will cause the egg contents to contract, causing any 'germs' on exterior surface of egg shell to be pulled into the interior of egg thru the shell pores. Using warmer water will do the opposite.

I don't use any soap or other cleaning/sanitizing agent, just rotate in my hands to 'scrub' all surfaces area of egg shell. Then I air and towel dry before placing in the fridge.

If you are washing eggs for sale to the general public, other requirements may apply, so check your state regulations.
