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.
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? :)
