The first really big egg for me was a 2.7 oz. from an EE. That was just before all 6 of my girls stopped laying (for the most part) for the winter. I had several really big ones, biggest of which was 3.4 ozs., that was a double yolk, the others were singles. I was pretty exciting, getting such wombo eggs once every third or fourth day for about 10 days, then they stopped altogether. So, I've been assuming that mine will do this before they quit for the winer.
