I am new to the world of Chickens and I have a question. My neighbors have a hen and a rooster and no coop the chickens just roam around all day. So my questions are Do chickens run away? Do you think I will be able to just let them roam around all day and then lock them up at night? Does this mean I may not have to freak out about predators? I built a coop and it is Predator proof (or the best possible) any help would be great. Thank You
