I have been following some of the conversation about double and triple yolked eggs, and watched the video on another thread of twins hatching, but hadn't had the double yolk experience - until Saturday! I couldn't believe it when I opened the door to the nest boxes. My hens are all young and one just starting laying. I don't know who did it, but I looked to see who was walking funny! I did circumfrence measurements too, but forgot to bring them to work. I'll post an edit tomorrow with that info. DH wash shocked! But, that didn't stop him from enjoying eating it on Sunday morning.
