I have an Olive Egger roo that I'm trying to decide if I am going to keep. If I bred him over my Easter Eggers, what are the chances that the offspring could lay an olive egg? I purchased Olive Egger eggs for hatching so I could have some olive eggs, but only 1 hatched and it's a rooster!
My numbers may be off but if your hens lay blue eggs you should get half blue egg layers and half olive eggers, assuming the hens have two blue egg genes. I'm in the same quandary I have mostly Easter eggers and a few Ameraucanas. I have a young cockerel whose mother was a black copper marans. Since we had a fox problem when the eggs were in the incubator, and that was the only marans egg in, I was really hoping for a pullet. It seems the fox targeted my dark egg layers so now I'm considering keeping this guy so I can make more olive eggers. I'm sitting on the fence about it.
