Solved! OE - Cockerel or Pullet?

50% of his female offspring should lay olive eggs and 50% brown. Remember that numbers don't always work out like that - you could get almost all brown layers with only a couple green layers (or less) or it could go the other way around.

If the rooster has one blue egg gene and one white egg gene, you may be correct. However if the rooster has two blue egg genes each of his offspring will have one blue egg gene and one white egg gene and whatever brown egg genes they get from the hens. When you mix the blue egg gene with brown egg genes you get green or olive colored eggs. The offspring are getting their white egg gene from their brown egg laying mothers.

Yes. But the OP gave the cross - Marans rooster over Ameraucana hen. Since both were pure, he has one allele for blue egg shell color and one for white. The only two shell colors are blue and white - brown is basically a 'spray paint' over the shell, the result of a combination of other genes, making a white shell brown on the outside and a blue green or olive.

Yes if that is his heritage he can definitely make more brown egg layers and a few olive egg layers.

Still a nice cockerel

Thanks! I'm going to keep him and see what he throws. I predict that 100% of his offspring will be ... chickens.
