My mom just called all excited about one of the eggs I gave her. She said it had another complete egg inside of it. I told her I had just read a thread on here about eggs within eggs which also had a link to an ag site that showed pics. https://www.backyardchickens.com/forum/viewtopic.php?id=35783 I told her the info said they were rare and the egg inside was usually small and had no yolk. She said the egg inside was only slightly smaller than the outer egg and BOTH had yolks. I asked her if she thought to preserve the moment in history and she said "no, we ate them". Oh well - you would have known it - could have been rich like that family in Mexico with the rare green egg laying hen. Guess I'll have to wait and see if we get another one. Only problem is that I give almost all our eggs away. I call it my egg ministry. I give them to the maids, AT&T guy, propane guy, termite inspection guy - just about anyone who shows up here for any reason leaves with at least a dozen eggs. So I may never know if I have a rare double egg laying hen and if so, which one. No wonder they are all hiding their nests lately.
