This is my first backyard flock and I am learning a lot about chicken behavior not only by direct interactions but through surveillance cameras in the coop and around the run. Respected references state that most will lay early in the morning. But my 6 gals never got the message. They lay as early as daybreak and as late as sundown. Each has a pattern of laying a little later each day until a late egg, then skip the next day, and the following day lay very early, and so on. The biggest surprise was a sundown egg laid while the others were already on the roosts!
