Hi I am new to raising chickens and I have a question. My Rhode Island Red hens are just under 5 months old and last week they began to lay their first eggs. I was a little taken back because I was expecting to get some nice dark brown eggs but theirs are a light ivory color. Is this normal for young hens? Will then start to produce the typical brown egg in the future? Was I ripped off and not sold Rhode Island Red chicks? Thanks!
