    Using a French Black copper Marans Roo on other breeds (isa brown, RIR) to increase egg production but keep dark eggs? Is it possible?

    No I said a Marans crossed to a regular shade brown egg layer would not produce offspring that would entirely lose the genes responsible for the dark eggs but would lose some. The offspring should lay eggs darker then regular brown but not as dark as a Marans. There was another poster that...

    You said you had a BCM Ameracauna cross and posted a brown egg that it laid. What I'm saying is that the Ameracauna parent to that bird wasn't a true Ameracauna. Couldn't have been to produce a brown egg laying offspring.

    Oh I believed it came from a Marans egg but your Ameraucana rooster isn't a true/pure Ameraucana

    Don't Polish lay white eggs? So if the cross produced regular brown egg layers then that seems like yes some brown genes were lost but some were not. That should also show there's more then one gene in play. Your second post is also odd. A BCM crossed with an Ameraucana would produce a green (of...

    ☝️ This doesn't sound right. What was your experience? Last I heard there were a couple dozen or more genes that contributed to the brown coating. Some dominate, some recessive and a couple sex linked. I worked on Olive Eggers years ago and when the Marans were crossed with blue egg layers some...
