I am curious as to the 'timing' of my girls' laying habits. They never seem to cackle until late in the day. it's now cold and dark most of the mornings, and we turn on a light at about 7-8 am. they still don't start making noise until 3-4 hrs later. and I have a few that like to lay an egg around suppertime. They had the same patten in the summer when it was sunny early. Best guess? or do the wise ones know?
