Could this be a guinea fowl egg?

[Hablo]

The left one is a Marans egg (65g) and the right one the unknown type of egg (55g).
Or is it perhaps a Sundheimer or a Jersey Giant egg since we have these races since recently.
I know, guineas should lay their eggs outside the coop but perhaps my guinea lady doesn't?

Not shaped like a Guinea Fowl egg.

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

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.

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.

Thanks. Looks to me like a normal chicken egg.

They're not. Texture of the shell is different, & are rock hard.

Alittle bit more true to color in this picture.

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.

That's a Guinea Egg. Alittle rough looking.

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

Is the texture uneven? There are little dots on the shell. Can you feel them with your fingers?
