My hen house is an old building, built sometime in the 1930's. It has a window, and a homemade wood door of planks. A few of these planks have knot holes , that have perfect views of the nest boxes. I find myself peaking through the holes a few times a day, looking for hens on the nest. I also use the window. I'm spying on my chickens, trying to figure out who has started laying, because I have a flock of young pullets. Is this acceptable human behavior, or am I obsessing?
