Well, I tell mine stories about chicken noodle soup! Sometimes that straightens them up.
I will state that hidden nests can be incredibly hidden in plain sight. I don't have a camera - but I have gone down to the coop with a book and a cup of coffee and just sat there quietly, waited and watched, realized the were going into the coop, but when I went in, they were not there. Hidden under a bench, back behind a board, was a nest of 22 eggs! Or once, there was an old stump, with a bit of hay blown up along the side, and UNDEr that was a nest. Just saying.
Right now, I have three pullets hatched in May - no eggs yet. If they don't lay by the end of November, I won't expect any until the end of January. Just not enough light.
In the summer, temperatures near or over 100 will affect my laying dramatically decreasing that. In the fall, a lot of cloudy days, will reduce it too.
