What is wrong with these eggs? Is this normal?

[Rootie]

Hello chicken family!
I am not sure if this is the right thread to post in or not. Please forgive me if not.
I am new to the chicken family so this may sound like a elementary question. What is wrong with these eggs?? Once I collect the eggs I put them in a basket on my counter top, out of direct light and not washed. With in a day or two they start to have these spots on them. Is this normal?? Thank you in advance for your help.

Are the spots uniform around the egg or simply on the top side, the side facing out of the basket?

If they aren't present from the hen, they are likely absorbing something or being splattered by something from the kitchen.

I've never noticed that with mine, and I let my personal eating eggs sit out on the counter too.

I can't imagine its anything evil.

My guesses.

Those are normal eggs but with poor eggshell quality. Your birds need more calcium and vitamin D. The best source of calcium is calcium carbonate for birds. It's the most easily ingested. Oyster shell only goes into their system as it is "rinsed off the pieces in the gizzard. For good calcium you need to buy some Limestone calcium that is formulated for animal feed. If you have a local coop they probably either have some or can get it. It's cheap!
