We just finished our coop last month, and my husband installed a ceiling fan (finally!) for ventilation a few days ago. We turned it on during the day to test it out, and the chickens completely freaked out, so we turned it off. When we went out to close up the coop later that evening, all 14 chickens were huddled outside of the coop on the ramp leading to the run, even though the fan was off. The fan has 4 different speeds and is completely noiseless. Does anyone know if there is any chance they will get used to it? Like if we put it on low during the night when they're sleeping so they don't witness it going from still to moving? I think that's what freaked them out the most was just that it was inanimate and then suddenly became animate.
