Could this be a guinea fowl egg?

As the shell should be really hard to break, I beat it with my finger nail, but it cracked a bit. That's why I put it into my pan. And as you can see, the yolk looks completely different.

New layers can have glitches within their reproductive systems before things become normal. There's actually no yolk in that, just the thick Albumin, & thin Albumin. Glitches can effect shell hardness as well.

One of my new layers years ago would lay double yolkers constantly, one time a Triple yolker.

You're welcome.
Do you provide oyster shells for them?

No, I don't, as all of the chicken roosters we butchered had little stones in their stomach. Should I?

Oyster Shells let the ladies regulate their calcium intake for strong eggshells.

Chickens don't have stomachs. That was most likely grit they picked up to help grind their food.

That's a Guinea Egg. Alittle rough looking.

While the color is right, the shape is wrong and easily broken doesn't fit either.

All birds eat "grit" which will be found in their gizzards. It is how they grind food that needs processed before digestion since they can't chew.

Oyster shell is soluble and dissolves and does not act as grit. It's highly unlikely that your roosters were eating the oyster shell but your hens do need it.

I suggested the oyster shell due to the fact the shell was thin.
Shape is right. This was from a first time layer, was my first guinea egg.

We feed our chickens their own shells which we break before so that they have enough calcium for their eggs.

Feeding back the egg shells only is not likely to provide sufficient calcium on its own.
