I used to be able to tell who layed which egg. But, now that winter is here and a couple stopped laying and couple started laying I'm having a heck of a time determining who layed what between my Brahma mix, my gold laced Wyandotte, and my two red sex links. The EE and my Australorp are so distinctive that there is no mistaking them. My two Legurns lay white eggs and when they both lay, which they did everyday all summer, I could tell who layed which egg by the size of the egg. But now that they are laying sporadically it's hard to tell. I guess it really doesn't make any difference, I just like to keep track. Today I got 5 eggs from 8 hens so I'm not complaining. I mean, it's the dead of fake winter and they are laying.
