I'm no expert and the closest thing I can say to help is if the hen has red earlobes then it will lay brown eggs and white earlobes will lay white. So, I would only guess since the parents would be one of each it would be a toss up. Maybe someone else knows for sure
I didn't think about looking at the earlobes. Thanks. I don't know if that's possible with the young chicks that I have, but I will take a look. I am trying to decide if I want to keep them. I don't need any more white egg layers, so I was hoping they might take after the RIR and lay brown eggs.
