Example of what you might get for eggs to help boost ya for the day... 😁 these are from a couple of my Marans that have lightened up in their laying cycle but throwing speckles....
You may get a varying mixture of both depending on your hens egg color genetics. What I was trying to say was if the mother was a dark brown layer, more than likely all chicks will lay lighter colored eggs than the mother because the roo came from a lighter egg.
There's always variables of...
Not a wizard at color genetics but your roo should lighten up your hens darker eggs. If your roo came from a dark egg and you breed him to a dark layer he should darken her eggs. Or the same as breeding a Black Copper Marans roo over a green egger will make Olive eggs...
So to speak without all...
