Man alive I about freaked out when I saw that egg in the nest box.. It happened a couple weeks ago during the freakish cold spell we had here in NE Ohio it was like -14 plus windchill which was something like -25.. anyway my white leghorn pullet who will just be turning a year old laid me the largest white egg I have ever seen.. it surpasses a jumbo sized egg by leaps.. It literally looks like a large goose egg. It won't even fit in the jumbo egg cartons I have.. I had another hen lay a brown egg in this size range during this cold snap too.. not as large but close.. I am going to carefully blow out the contents and save the shells as I do with odd colored/unique shells that I collect. This by far is a keeper and I suspect really had to hurt coming out!!!! She is a laying machine!! And the size of the eggs she lays compared to her size is amazing.. she really is not that large of a hen. I may try to take a photo of my regular eggs and this one for comparison and post it.. it really is amazing.
