Yep. I have a small lined notebook next to my kitchen scale. In it I write the date, who laid (or at least who I think laid, I can tell for most of them but I haven't truly figured out which of the SS girls lay the long skinny eggs and which one lays the more round eggs), and any interesting notes such as if the egg was laid from the roost or in the run or if it was cracked or had some other abnormality. I also record the weight of the egg. In the beginning, I just recorded the days that they laid. But since all but one or two have stopped laying for the molt I have also started recording days with "no eggs" in the book too. I only have 7 hens (and only 6 of them are any real good at laying), so it's not so hard. If I had too many more though I might just record the number of eggs and weights and breeds or color that were laid.
