so do my chicks will laying olive and brown eggs in future???? all of them hatched from brown eggs

thank you

The problem with giving you a clear concise answer is that roosters don't lay eggs and the olive egger was a rooster. There are different ways to make what someone may call an olive egger. In some ways you can be certain that he actually has a blue eggshell gene and about half his offspring will get that gene. That's only the first generation cross if you are sure of his parents. If there is any question about his parents or if he is a second generation cross all that is out of the window. Even if he hatched from a blue or green egg you don't know for sure that he has that blue eggshell gene.

There are three possibilities. He might have two blue eggshell genes if he is a second or later generation cross. In that case all of his pullets will lay green and probably olive eggs hatching from those brown eggs. He might have zero blue eggshell genes if he is a second or later generation cross. In that case none of his pullets will lay olive eggs, all will be brown. He might have one blue eggshell gene whether he is a first, second, or later generation cross. In that case about half his pullets should lay brown and half olive.

I don't know enough about that rooster to be able to tell you anything for sure. Good luck!

I like your reply it was helpful
what i was told that chicks are 75% marans 25% olive egger.. im newbies i have no idea how chicken gene. work and those rainbow colors work too

If a F1 olive egger is crossed with a Maran you get F2 olive Eggers which lay darker olive eggs.
A olive egger is a Ameraucana/Marans cross.

A olive egger is a Ameraucana/Marans cross.

That's your definition. It could be an Ameraucana/Welsummer cross, they should lay an olive colored egg also. Or have one parent that is an Auracana or possibly a Cream Legbar for the blue eggshell gene bred with a dark brown egg laying breed. It could be any hen or pullet that lays an olive colored egg, regardless of background. It could be a chick hatched from an olive egger parent, male or female, whatever the background of that parent.

It would be nice if Easter Eggers and Olive Eggers could be so neatly described but that's not how real life works.

Ok but technically a olive egger *should* be a Ameraucana or araucana/marans but yes it could be any blue egger/any brown egger.

That's about as clear as mud. I could see a scenario where the hens that laid the eggs are pure Marans and the father was a cross between a Marans and a blue egg laying breed, whether that blue egg laying breed was Ameraucana, Araucana, Cream Legbar, or something else. If that is the case then about half of your pullets should lay olive eggs. If it is different then I just don't know.

Without a basic understanding of how genetics works it can be hard to understand. There are two genes at the gene pair that controls the base color. Blue is dominant. That means if one or both of those genes are blue, then the base color is blue. If neither is blue then it defaults to a base white color. Green or brown is brown added on top of base blue or white. The darker the brown the darker the eggs.

Base blue + brown = green
Base blue + no brown = blue
Base white + brown = brown
Base white + no brown = white

There are a lot of different gene pairs that control brown so the shade you get just depends on which of those genes are present. That's why you can get so many different shades of brown and green. There is only one gene pair that sets the base color as blue or white.

Chicks get half their genetics from their mother, half from their father. If one parent has the same gene at both genes in that gene pair then you know what the chick will get from them. But if it is split for that gene at that gene pair you don't know which any specific chick gets.

The Marans hens that laid those eggs have base white, no blue at all. I'm not sure what the father has.

Um actually an olive egger over maran is a BC1 Not an f2. F2 is breeding two f1s together
