Making of an Olive Egger

[ChocolateMouse]

I don't know if anyone is still watching this, but I have what I think is called an F2 olive egger. What happens if I breed her to a Marans? Will the eggs be darker, or brown?

Depends on her genetics.

If she lays olive eggs she has at least one blue gene. Marans have none.

It's likely that if she has one blue gene half will be darker green half will be dark brown.
If she has two blue genes they will all be darker greens.
And in this case because the marans has no blue genes, all the green egg laying chicks would be Oo regardless of if mama carried one or two 'O's.
