I have a shed sized chicken coop and a big run. Recently I built an over hang on one side of the coop so I can hang garden tools etc... anyways the coop window is now under that overhang. It's great in the day because the coop is shaded, plenty of light still. By late evening/night the coop is pitch black now and fast. The chickens aren't used to it and when they go in to roost they can't roost because of their vision. I found one squaking and running in the outside pen at dark, one on the coop floor, one in the nest, and only one on the roost. Will they adjust to this change eventually?
