Can I cross my Starlight Olive Eggers back towards the Prarie Bluebell breed of chicken

[Judykaymayes]

I am wanting to know if there would be any crossbreeding that could be done to get Starlight Eggers back to Prarie Blue Bells?
Thank you

The problem with that is that brown tint genes are tenacious and there are a lot of them. I think over 13. Also, it can be hard to tell when a line if chickens has stopped having tint genes, as very light green eggs can resemble blue eggs. All in all, it would take a good few years of breeding, and even then you might not accomplish it.
