Hatching olive eggs

So, it’s possible to breed true for olive eggs…if the correct parents (homozygous B) are selected in the F2?
Does anybody here have olive eggers that are f3+?
I stopped after f2 a year old and my hen never layed so i processed her and called it quits even grabbing two olive eggers like f3s you still have a chance of brown unless you bc1 and so on

If I understand correctly… Those 25% of f2s that are homozygous for the blue gene would not produce brown eggs, only shades of green.

Of course those f2 roosters and hens would have to be tested to know if they had 2 copies of the blue egg gene.

It would make more sense imo to stabilize the olive egg trait before back crossing to the blue egg layer or the dark brown layer.
