You will start to recognize the different eggs from different hens. Size, shape and spot pattern will be surprisingly consistent. One of my big girls always lays a small, pointy egg with small evenly scattered spots. Another always lays a large one with a more oval shape, large irregular splotches that cover 80% of the cream background. One person here even put food coloring in the vents of the hens so they could tell who was laying, and which eggs came from each hen.
I am not going to get that crazy (dye in the vents), but I do think it would be cool to see if specific hens tend to lay in the same area each day. So far I am seeing a trend of near or in the dog house each afternoon/evening. I also have noticed that the first hen to begin laying was more oblong and pointy, and the second hen to begin laying has more rounded eggs. The rounded ones also seem to weigh a little less. I have not noticed a trend on coloring. And I have no idea which birds are the ones laying. I am sure once I start getting more than 2 per day, all ability to track will go out the window. Hahaha.
