Here's a picture of our first egg that we got on July 8th of this year. Once we found our first egg, we switched the girls to egg laying feed. We've always had oyster shell available to them to feed at will. Our girls (RIW & NHR) who were born March 10th, were two days shy of 4 months old when we found our first egg. I can't tell you though which breed gave us that first egg.
