OK, thanks you guys, that at least gives me an idea. I figure there is more info on chicken genetics, and it is potentially similar to duck genetics. Or potentially very different.
How reliably is egg color passed on? I heard in EE's green is dominant?
I'm wondering about ducks though. Is it worth it to incubate colored duck eggs, if I want to get ducks that will lay colored eggs?
Thanks in advance to anyone with any info!
