I have a coop for my free range flock. But snow has started blowing in it and they won't come out. I shut the door and now its not near as bright in there. Will this affect their eyes at all. I don't have lights in the coop and don't plan too so i know my egg count is going to drop. Also there's not a whole lot of space because they usually just sleep in it how can i keep them from getting bad habits? On nice days ill leave the door open so they can come and go as they please. Do i have to make sure they have food all day or is feeding them twice a day enough? Not happy dumb weather.
