My RIR was the last to start laying and my Barred was second to last. They started about...maybe 3 weeks ago?Wow, that is a freaky egg! It does look like maybe a failed double yolker? Only one of my girls has laid so far, and out of her three eggs, the first had a small bloodspot, the second was a double yolker, and the third was normal and large. Is yours a new layer?
