Two-tone / marbled eggs?

[AndalusianBlueMomma]

Hello - one of my girls laid this egg which surprised me. Do they run out of pigment or something? Is something lacking in their diet? I feed the layer feed, oyster shell, meal worms as treats, fresh veggies, and they also free range during the day (in a secure area). I have 2 Australorps and a Brahma that are laying, and an Andalusian Blue who is molting and not laying right now.
Thanks!

I get an egg like that every now and then. It seems to work out so I don't worry about it any longer.
If your feeding them well and everyone seems healthy, I wouldn't worry too much.

Weird eggs happen sometimes, I wouldn't know the cause of that though.

This is one of my favorites (the blue one) of all time. She laid a few of these before her ink cartridge regulated itself.

Looks possibly like uneven bloom (the whitish stuff), otherwise could just be a one off pigment glitch.

Ditto Dat.

Could be calcium too.
Nothing to worry about.
